Abstract
Overview
ISO/IEC 15731:1998 specifies a standardized physical and magnetic tape format for information interchange using a 12.65 mm wide magnetic tape cassette - the Digital Tape Format‑1 (DTF‑1) using helical‑scan recording. The standard defines two cassette sizes (Type S and Type L), tape materials and dimensions, recording methods, track formats (helical and longitudinal), signal quality metrics and reference calibration tapes (MSRT/SSRT). The format supports variable‑length logical records, high‑speed search and registered algorithms for lossless data compression.
