  • MINI-CARTRIDGE ADAPTER FOR ADAPTING A MINI-CARTRIDGE TO AN INDUSTRY STANDARD TAPE CARTRIDGE FORMAT
    Publication number: 20010055178
    Abstract: A tape mini-cartridge is functionally compatible with a larger industry standard tape cartridge. A mini-cartridge adapter adapts the mini-cartridge to be compatible with a standard tape drive by presenting the standard structural and functional appearances to the tape drive as presented by the larger standard tape cartridge. Since the standard cartridge has a plurality of structural elements including reel locks, leader buckle guide, and write protect flag engaged by the standard drive, the cartridge adapter effectively transfers these engagements and forces to and from the mini-cartridge in a manner providing full structural interchangeability with the standard tape cartridge.
