Lou Ottens
Lodewijk Frederik Ottens (21 June 1926 – 6 March 2021) was a Dutch people, Dutch engineer and inventor, best known as the inventor of the cassette tape, and for his work in helping to develop the compact disc. Ottens was employed by Philips for the entirety of his career. Early life Ottens was born in Bellingwolde on 21 June 1926. Ottens showed an interest in technology and tinkering from an early age. While in his teens, during the Netherlands in World War II, German occupation of the Netherlands in World War II, he constructed a radio that he would use to secretly listen to ''Radio Oranje'' broadcasts. In order to avoid Nazi Germany, Nazi German Radio jamming, jammers, Ottens constructed the radio with a primitive directional antenna. After the war, Ottens began attending the Delft University of Technology, where he studied mechanical engineering. While attending university, Ottens worked part time as a drafting technician for an X-ray technology factory. He graduated in 19 ...

Drafting Technician
A drafter (also draughtsman / draughtswoman in British and Commonwealth English, draftsman / draftswoman or drafting technician in American and Canadian English) is an engineering technician who makes detailed technical drawings or plans for machinery, buildings, electronics, infrastructure, sections, etc. Drafters use computer software and manual sketches to convert the designs, plans, and layouts of engineers and architects into a set of technical drawings. Drafters operate as the supporting developers and sketch engineering designs and drawings from preliminary design concepts. Overview In the past, drafters sat at drawing boards and used pencils, pens, compasses, protractors, triangles, and other drafting devices to prepare a drawing by hand. From the 1980s through 1990s, board drawings were going out of style as the newly developed computer-aided design (CAD) system was released and was able to produce technical drawings at a faster pace. Many modern drafters now use c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video 2000
Video 2000 (also known as V2000, with the tape standard Video Compact Cassette, or VCC) is a consumer videocassette system and analogue recording standard developed by Philips and Grundig to compete with JVC's VHS and Sony's Betamax video technologies. It was designed for the PAL color television standard, but some models additionally handled SECAM. Distribution of Video 2000 products began in 1979 exclusively in Europe, South Africa and Argentina and ended in 1988. Although some initial models and advertising featured a mirror-image "VCR" badge based on the logo of Philips's earlier Video Cassette Recording (VCR) system, Video 2000 was an entirely new (and incompatible) format, which incorporated many technical innovations. Despite this, the format was not a major success and was eventually discontinued, having lost out to the rival VHS system in the videotape format war. The Video Compact Cassette Philips named the videotape standard Video Compact Cassette (VCC) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LP Record
The LP (from "long playing" or "long play") is an analog sound storage medium, a phonograph record format characterized by: a speed of rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the "microgroove" groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk. Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it remained the standard format for record albums (during a period in popular music known as the album era) until its gradual replacement from the 1980s to the early 2000s, first by cassettes, then by compact discs, and finally by digital music distribution. Beginning in the late 2000s, the LP has experienced a resurgence in popularity. Format advantages At the time the LP was introduced, nearly all phonograph records for home use were made of an abrasive shellac com ...

Philips Natuurkundig Laboratorium
The Philips Natuurkundig Laboratorium (English translation: ''Philips Physics Laboratory'') or NatLab was the Dutch section of the Philips research department, which did research for the product divisions of that company. Originally located in the Strijp district of Eindhoven, the facility moved to Waalre in the early 1960s. A 1972 municipal rezoning brought the facility back into Eindhoven, which was followed some years later by Eindhoven renaming the street the facility is on into the ''Prof. Holstlaan'', after the first director.Google Maps location of the facility In 1975, the NatLab employed some 2000 people, including 600 researchers with university degrees. Research done at the NatLab has ranged from product-specific to [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compact Cassette
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge an ...

IFA Berlin
The IFA ( ) or Internationale Funkausstellung Berlin (International radio exhibition Berlin, a.k.a. 'Berlin Radio Show') is one of the oldest industrial exhibitions in Germany. Between 1924 and 1939 it was an annual event, but from 1950 it was held every other year until 2005. Since then it has become an annual event again, held in September. Today it is one of world's leading trade shows for consumer electronics and home appliances. It offers the opportunity to exhibitors to present their latest products and developments to the general public. As a result of daily reporting in almost all the German media, the radio exhibition and the showcased technology receives a large amount of attention around the globe. In the course of its history, many world innovations were first seen at the exhibition. IFA is "Europe’s biggest tech show". 245,000 visitors and 1,645 exhibitors attended IFA 2015.

RCA Tape Cartridge
The RCA tape cartridge is a magnetic tape audio format that was designed to offer stereo quarter-inch reel-to-reel tape recording quality in a convenient format for the consumer market. It was introduced in 1958, following four years of development. This timing coincided with the launch of the stereophonic phonograph record. It was introduced to the market by RCA in 1958. The main advantage of the RCA tape cartridge over reel-to-reel machines is convenience.Stereo Goes Back On Tape Popular Mechanics, September 1960, P. 205 The user is not required to handle unruly tape ends and thread the tape through the machine before use, making the medium of magnetic tape more friendly to casual users. In addition, since the cartridge carries both supply and take-up reels, the cartridge does not have to be rewound before th ...

Cassette Recorder
A cassette deck is a type of tape machine for playing and recording audio cassettes that does not have a built-in power amplifier or speakers, and serves primarily as a transport. It can be a part of an automotive entertainment system, a part of a portable mini system or a part of a home component system. In the latter case it is also called a component cassette deck or just a component deck. A "tape recorder" is a more generic term to identify a device that usually has a self-contained power amplifier and either has a built-in speaker or comes packaged with one. History Origins The first consumer tape recorder to employ a tape reel permanently housed in a small removable cartridge was the RCA tape cartridge, which appeared in 1958 as a predecessor to the cassette format. At that time, reel to reel recorders and players were commonly used by enthusiasts, but required large individual reels and tapes which had to be threaded by hand, making them less-accessible to the casu ...

Loudspeakers
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker ''drivers'', an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone; indeed the ''dynamic speaker'' driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such a ...

Tape Recorders
An audio tape recorder, also known as a tape deck, tape player or tape machine or simply a tape recorder, is a sound recording and reproduction device that records and plays back sounds usually using magnetic tape for storage. In its present-day form, it records a fluctuating signal by moving the tape across a tape head that polarizes the magnetic domains in the tape in proportion to the audio signal. Tape-recording devices include the reel-to-reel tape deck and the cassette deck, which uses a cassette for storage. The use of magnetic tape for sound recording originated around 1930 in Germany as paper tape with oxide lacquered to it. Prior to the development of magnetic tape, magnetic wire recorders had successfully demonstrated the concept of magnetic recording, but they never offered audio quality comparable to the other recording and broadcast standards of the time. This German invention was the start of a long string of innovations that have led to present-day magnetic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turntables
A phonograph, in its later forms also called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910) or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogue recording and reproduction of sound. The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record". To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones. The phonograph was invented in 1877 by Thomas Edison. Alexander Graham Bell's Volta Laboratory made se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
