Mini Compact Disc
Mini CDs, or pocket CDs, are CDs with a smaller diameter and one-third the storage capacity of a standard 120 mm disc. Formats Amongst the various formats are the *Mini CD single, a small disc. The format is mainly used for audio CD singles in certain regions (singles are sold on normal 120 mm CDs in many countries), much like the old vinyl single. An 80 mm disc can hold up to 24 minutes of music, or 210 MiB (210 × 220 bytes) of data. They are often referred to as ''Maxi CDs'' in some countries. **The low density version holds 18 minutes, or 155 MB. **Other formats are 185 MB (21 mins), which has the same data density as a 650 MB full-sized CD, and 210 MB (24 mins), with the same data density as a 700 MB full-sized CD, used for "Pocket" data storage. (see also miniDVD) *Business card CD (or "b-card"), a truncated (to the shape and size of a business card) disc with a storage capacity from 30 MB ...

Mini CD Vs Normal CD Comparison
The Mini is a small, two-door, four-seat car, developed as ADO15, and produced by the British Motor Corporation (BMC) and its successors, from 1959 through 2000. Minus a brief hiatus, original Minis were built for four decades and sold during six, from the last year of the 1950s into the last year of the 20th century, over a single generation, as fastbacks, estates, and convertibles. The original Mini is considered an icon of 1960s British popular culture. Its space-saving transverse engine and front-wheel drive layout – allowing 80% of the area of the car's floorpan to be used for passengers and luggage – influenced a generation of car makers. In 1999, the Mini was voted the second-most influential car of the 20th century, behind the Ford Model T, and ahead of the Citroën DS and Volkswagen Beetle.

''Orange Book'' also introduced the standard for multisession writing. *CD-MO (''Magneto-Optical'') ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compact Disc
The compact disc (CD) is a Digital media, digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. In August 1982, the first compact disc was manufactured. It was then released in October 1982 in Japan and branded as ''Compact Disc Digital Audio, Digital Audio Compact Disc''. The format was later adapted (as CD-ROM) for general-purpose data storage. Several other formats were further derived, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video CD (VCD), Super Video CD (SVCD), Photo CD, Picture CD, Compact Disc-Interactive (CD-i) and Enhanced Music CD. Standard CDs have a diameter of and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 mebibyte, MiB of data. Capacity is routinely extended to 80 minutes and 700 mebibyte, MiB by arranging data more closely on the same sized disc. The Mini CD has various diameters ranging from ; t ...

Shaped Compact Disc
A shaped compact disc is a non-circular compact disc. Examples include business card CDs, CDs in the shape of a star, a map of a country, interview material and more. These discs are usually made for marketing purposes and are properly read by most CD-ROM drives (and audio CD players, although custom-shaped CDs tend to contain less data). There are many companies that sell CDs with custom shapes. Unlike Mini CDs, which are smaller, but still circular versions of normal CDs, custom CDs can be any number of shapes, even more complicated shapes like gears with dozens of teeth, but are generally smooth and with rounded edges, such as ovals or rounded rectangles. A logo can be printed on a shaped CD, in the same way common audio CDs and CD-ROMs are labeled. Shaped CDs are produced in one of two ways. A special mold can be made and used to "stamp" CDs (or DVDs) as part of the precision injection molding process that is used to make CDs and DVDs. Because of the initial cost involved ...

GameCube Game Disc
Nintendo optical discs are physical media used to distribute video games on three of Nintendo's consoles that followed the Nintendo 64. These are the GameCube Game Disc, Wii Optical Disc, and Wii U Optical Disc. The physical size of a GameCube Game Disc is that of a miniDVD; the Wii is based on DVD format, and Wii U Optical Discs are based on Blu-ray format. To maintain backward compatibility between generations of game consoles, GameCube discs are compatible with the first model of the Wii, and Wii Optical Discs are compatible with the Wii U. A burst cutting area is located at the inner ring of the disc surface. All official discs and their formats were manufactured and developed by Panasonic. In 2017, Nintendo discontinued disc-based media in favor of game cards for the Wii U's successor, the Nintendo Switch, although it would license several more physically released Wii and Wii U games for many more months, with the last one being a port of '' Shakedown: Hawaii'' to both cons ...

MiniDVD
MiniDVD (also Mini DVD or miniDVD) is a DVD disc which is in diameter. Most MiniDVDs hold 1.4 GB of data, but there are variants that hold up to 5.2 GB. The MiniDVD is also known as a "3 inch DVD", referring to its approximate diameter in inches. The 8 cm optical disc format was originally used for music CD singles, hence the commonly used names CD single and miniCD. Similarly, the manufactured 8 cm DVDs were originally used for music videos and as such became known as DVD single. MiniDVD capacities Recordable 8 cm discs are commonly used in DVD-based camcorders. The most common MiniDVDs hold 1.4 GB of data, but there are variants that can offer up to 5.2 GB of storage space, through a combination of dual layers and sides. Mini DVDs are also available in +R, +R DS, +R DL, +R DL DS, +RW, +RW DS, -R, -R DS, -R DL, -R DL DS, -RW, and -RW DS variants, just like their full sized counterparts.

MiniDisc
MiniDisc (MD) is an erasable magneto-optical disc-based data storage format offering a capacity of 60, 74, and later, 80 minutes of digitized audio. Sony announced the MiniDisc in September 1992 and released it in November of that year for sale in Japan and in December in Europe, North America, and other countries. The music format was based on ATRAC audio data compression, Sony's own proprietary compression code. Its successor, Hi-MD, would later introduce the option of linear PCM digital recording to meet audio quality comparable to that of a compact disc. MiniDiscs were very popular in Japan and found moderate success in Europe; although it was designed to be the successor of the cassette tape, it did not manage to mass replace it globally. By March 2011 Sony had sold 22 million MD players. Sony has ceased development of MD devices, with the last of the players sold by March 2013. Market history In 1983, just a year after the introduction of the Compact Disc, Kees ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bootable Business Card
A bootable business card (BBC) is a CD-ROM that has been cut, pressed, or molded to the size and shape of a business card (designed to fit in a wallet or pocket). Alternative names for this form factor include "credit card", "hockey rink", and "wallet-size". The cards are designed to hold about 50 Megabyte, MB. The CD-ROM business cards are generally used for commercial product demos, are mailed to prospective customers, and are given away at trade shows. Although the term "bootable business card" could be applied to any bootable CD-ROM in the business card form factor, it almost always refers to one which contains a compact Linux distribution generally containing a suite of system diagnostic and rescue tools and/or demos of specific packages. History In 1999 Linuxcare employee Duncan MacKinnon proposed the idea of producing and distributing such a card for an upcoming tradeshow. He and his team of volunteers (fellow employees) coined the phrase "bootable business card". The prem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IPod Photo
The iPod Classic (stylized and marketed as iPod classic and formerly iPod Video or just iPod) is a discontinued portable media player created and formerly marketed by Apple Inc. There were six generations of the iPod Classic, as well as a spin-off (the iPod Photo) that was later re-integrated into the main iPod line. All generations used a hard drive for storage. The "classic" suffix was formally introduced with the rollout of the sixth-generation iPod on September 5, 2007. Prior to this, all iPod Classic models were simply referred to as iPods; the first iPod released in 2001 was part of this line that would be called "Classic". It was available in silver or black from 2007 onwards, replacing the "signature iPod white". On September 9, 2014, Apple discontinued the iPod Classic. The sixth-generation 160 GB iPod Classic was the last Apple product to use the original 30-pin dock connector and the distinctive click wheel.

Universal Serial Bus
Universal Serial Bus (USB) is an industry standard that establishes specifications for cables, connectors and protocols for connection, communication and power supply (interfacing) between computers, peripherals and other computers. A broad variety of USB hardware exists, including 14 different connector types, of which USB-C is the most recent and the only one not currently deprecated. First released in 1996, the USB standards are maintained by the USB Implementers Forum (USB-IF). The four generations of USB are: USB 1.''x'', USB 2.0, USB 3.''x'', and USB4. Overview USB was designed to standardize the connection of peripherals to personal computers, both to communicate with and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports, and has become commonplace on a wide range of devices. Examples of peripherals that are connected via USB include computer keyboards and mice, video cameras, printers, portable media players, ...
