ABSTRACT:
A tape transport is disclosed which is for use with a magnetic tape cassette. Under some specific thermal conditions the tape cassette may develop gaps between the reel hubs and the tape rolls thereon, such gaps being likely to lead to the jamming of the tape through the hunting of a tape speed control servo built into the tape transport. Therefore, for removing the gaps, the reels are successively rotated in a direction for winding up the tape, after the tape cassette has been loaded in the tape transport and before reading or writing. Preferably, the pair of reels are simultaneously rotated in opposite directions for taking up a possible tape slack between the reels prior to gap removal.
