Section 3: Magnetic Media
Notes
3 It is difficult to differentiate between polyester and PVC tapes. For the purposes of care and handling, their needs are similar, meaning you do not need to identify these to properly care for them.
4 Acetate-based magnetic tapes benefit from temperatures at the lower end of this range, polyester from the higher end.
