適用范圍：This International Standard specifies the physical and magnetic characteristics of a 3,81 mm wide magnetic tapecartridge to enable interchangeability of such cartridges. It also specifies the quality of the recorded signals, therecorded format and the recording method, thereby allowing data interchange between drives by means of suchmagnetic tape cartridges. The format used is known as DATA/DAT-DC.This International Standard specifies two types of cartridges which, for the purpose of this International Standard, arereferred to as Type A and Type B.For Type A, the magnetic tape has a nominal thickness of 13 pm and a nominal length of up to 605 m.For Type B, the magnetic tape has a nominal thickness of 9 pm a length of up to 92.0 m.Information interchange between systems by means of this International Standard also requires the use, at aminimum, of a labelling and file structure and an interchange code which are agreed upon by the interchange parties.It is not within the scope of this International Standard to specify the labelling and file structure, or the interchangecode.
