    IBM Tape History – Session 1: Tape Media Bill Phillips, Ric Bradshaw, Andy Gaudet Moderated by: Tom Gardner Recorded: October 12, 2015 Tucson, AZ Also present off camera: Joel Levine Al Rizzi John Teale CHM Reference number: X7617.2016 © 2015 Computer History Museum IBM Tape History – Session 1: Media Introduction This is session one of five sessions held in Tucson, AZ, regarding IBM’s tape storage history. The five sessions are: 1. Tape Media (CHM catalog number: 102737992) 2. Overview of tape products and product management (CHM catalog number: 102737994) 3. 3480 tape drive (CHM catalog number: 102738021) 4. Linear Tape Open (LTO) Consortium (CHM catalog number: 102738023) 5. Recovery of tapes damaged in Challenger disaster (CHM catalog number: 102738025). IBM’s tape development began in the late 1940s in the Kenyon Mansion, Poughkeepsie, NY, (later IBM’s management training site)1 and moved to the then new Poughkeepsie lab in 1954. The first production units shipped in 1952. In 1965 production and development moved to Boulder, Colorado, then from Boulder to San Jose, California in 1973 and then back to Boulder in 19772. Its movement to Tucson, Arizona, was announced that same year and began in 1978. For additional history on tape products and technology see: 1. “History of Tape”, IBM Corp., 1978 ca., in CHM lot X7677.2016 2. “Innovations in the Design of Magnetic Tape Subsystems,” Phillips et. al., IBM JRD, September 1981, p. 691-99 3. “Data Storage on Tape,” W.
