ECMA-62

Data interchange on 12,7 mm 9-track magnetic tape - 32 ftpmm, NRZ1, 32 cpmm - 126 ftpmm, phase encoding, 63 cpmm - 356 ftpmm, NRZ1, 246 cpmm GCR

2nd edition, March 1985

This Standard ECMA-62 specifies the physical and magnetic characteristics of 12,7 mm, 9-track magnetic tape with reel, to enable interchangeability of such tapes. It also provides a format and three recording methods, thus allowing together with Standard ECMA-13 for Magnetic Tape Labeling full data interchange by means of such magnetic tapes.

The three methods defined in this Standard are:

  •  NRZ1 at the physical recording density of 32 ftpmm, yielding a data density of 32 cpmm,
  •  Phase Encoding at the physical recording density of 126 ftpmm, yielding a data density of 63 cpmm,
  •  NRZ1 at the physical recording density of 356 ftpmm, yielding a data density of 246 cpmm when Group Coded Recording is used.
