Hoagland was an assistant professor at Berkeley in 1954-55,


Career

In 1953, while still at Berkeley, Hoagland received a visit from Lou Stevens who had recently graduated from the CALDIC project and joined IBM's newly established west coast lab in

development and, because of the shared interest, Hoagand was invited to be a consultant on the project where he contributed to the magnetic component (heads and media) design and data-detection design. In 1956, Hoagland left Berkeley and formally joined the IBM San Jose laboratory shortly before the announcement of the IBM RAMAC. Hoagland conducted some of the first studies on track-following servo for HDD and wrote an early patent. Hoagland also conducted some of the first experiments with

In 2002, Hoagland acquired an original RAMAC from IBM. The restoration was started at IIST and subsequently completed at the Computer History Museum where the working RAMAC is now routinely demonstrated. An archive copy of the MDHC website is held at the Computer History Museum, Mountain View. In 2005, Hoagland retired from his position at Santa Clara University and moved to
