Abstract
Viscoelastic and shrinkage characteristics of alternative substrates for magnetic tapes are presented. The substrates evaluated include two polyesters (PET and PEN), an aromatic polyamide (ARAMID), a polyimide (PI), and poly(benzoxazole) or PBO. Thicknesses of the films range from 14.4 μm for PET to 4.4 μm for ARAMID. Results are also presented for ultra-thin magnetic tapes which use PET, PEN, or ARAMID as substrates. Based on their creep behavior (and relative cost), PEN or ARAMID appear to be suitable alternative substrates to PET
