  • Patent number: 6891695
    Abstract: A compact tape drive for reading and writing data on single reel magnetic tape cartridges. The compact tape drive has a tape threading mechanism that extracts the leader block from the magnetic tape cartridge and threads the leader block into a takeup reel that is located juxtaposed to the loaded magnetic tape cartridge. A separate magnetic tape wrap mechanism having a plurality of cooperatively operative tape wrap arms is also provided to position the magnetic tape around a set of tape guides and the read/write head. The magnetic tape wrap mechanism functions both to thread the magnetic around the takeup reel, spanning the space in front of the read/write head, and then to wrap the magnetic tape around the read/write head. In addition, the tape elevator, electronics and other standard tape drive assemblies are included in a predefined volume.

  • Patent number: 6441990
    Abstract: The present compact tape drive for reading and writing data on single reel magnetic tape cartridges that functions to implement the tape drive in a minimum predefined volume. The compact tape drive comprises a tape threading mechanism that extracts the leader block from the magnetic tape cartridge and threads the leader block into a takeup reel that is located juxtaposed to the loaded magnetic tape cartridge. The read/write head is located adjacent to the takeup reel and the loaded magnetic tape cartridge. A separate magnetic tape wrap mechanism comprising a plurality of cooperatively operative tape wrap arms is also provided to position the magnetic tape around a set of tape guides and the read/write head. The magnetic tape wrap mechanism functions both to thread the magnetic tape around the takeup reel, spanning the space in front of the read/write head, and then to wrap the magnetic tape around the read/write head.
