ABSTRACT:
Magnetic tape apparatus includes a master tape loop box magazine for temporarily storing a magnetic tape in a zig-zag condition, a transferring device disposed within the magazine for moving the tape to a tape outlet of the magazine, a detector for detecting the apparent density of the magnetic tape at the magazine outlet, and a travelling device which is operated only when the apparent density of the magnetic tape detected by the detector is below or less than a predetermined value. The apparatus is applicable to both endless and reel-to-reel type tape apparatus.
