Pertec
Pertec's most successful products were hard disk drives and tape drives, which were sold as OEM to the top computer manufacturers including IBM, Siemens and Digital Equipment Corporation, DEC. Pertec manufactured multiple models of seven and nine track half-inch tape drives with densities 800CPI (NRZI) and 1600CPI (PE) and phase-encoding formatters which were used by a myriad of original equipment manufacturers as I/O devices for their product lines.
In the 1970s, Pertec entered the computer industry through several acquisitions of computer producers and started manufacturing and marketing mostly minicomputers for data (pre)processing. This split up Pertec into two companies. Pertec Peripherals Corporation (PPC), which remained based in Chatsworth, California, and Pertec Computer Corporation (PCC), which was located at 17112 Armstrong Avenue, in Irvine, California.
