<p>This system makes use of a tape cassette helical scan tape transport (415-421) and 3480-type magnetic tape cartridge (401) as the data storage media. The merging of these two incompatible elements is accomplished by the use of a novel interface that implements a 'virtual tape cassette' using a tape cartridge (401) in a manner that makes this media compatible with the tape transport (415-421). The virtual tape cassette is implemented by providing a takeup reel (402) positioned with the magnetic tape cartridge (401) in a relationship that substantially matches the format of a magnetic tape cassette. A short tape threading arm (403) is used to retrieve the leader block (311) from the tape cartridge (401) and thread the magnetic tape (424) over a short tape threading path (423) to the takeup reel (402). Once the tape (424) is affixed to the takeup reel (402), the helical scan tape guide arms (415, 419) transport the length of tape (424) that is now exposed between the tape cartridge (401) and the takeup reel (402) to the rotary heads (416).</p> |
