The evolution of the high density 1/4" cartridge tape drive

A new cartridge tape recorder was designed to provide both a backup for fixed disc drives and an interchangeable media recorder for program loading and data logging. The drive employs a new format designed to use the streaming method of tape handling. Formatted capacities of 10 and 20 megabytes, with nominal backup times in the at-12 minute range, are included in the product family.
