ISO/IEC 20061:2001
Information technology -- 12,65 mm wide magnetic tape cassette for information interchange -- Helical scan recording -- DTF-2
Abstract
The electronic version of this International Standard can be downloaded from the ISO/IEC Information Technology Task Force (ITTF) web site.
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.
