Abstract

This International Standard specifies the physical and magnetic characteristics of magnetic tape cassettes, using magnetic tape

12,65 mm wide so as to provide physical interchange of such cassettes between drives. It also specifies the quality of the

recorded signals, the recording method and the recorded format, called Digital Tape Format-2 (DTF-2), thereby allowing data

interchange between drives by means of such cassettes. The format supports variable length Logical Records, high-speed

search, and the use of a registered algorithm for data compression.

This International Standard specifies two sizes of cassette. For the purposes of this International Standard the larger cassette is

referred to as Type L, and the smaller as Type S.

Together with a standard for volume and file structure, e.g. International Standard ISO 1001, this International Standard

provides for full data interchange between data processing systems.
