Cartridge reel with internal reel assembly lock

摘要

A data storage tape cartridge for a high speed tape drive. The tape cartridge encloses the tape reel having a drive hub that defines a reel lock. A ring of beveled gear teeth on the tape reel engage a ring of beveled gear teeth affixed to the tape cartridge for locking the reel to the cartridge. A spring biases the teeth into engagement. When the data storage tape cartridge is inserted into a data storage system, a drive hub engages the tape reel to shift the tape reel relative to the tape cartridge and disengage the rings of beveled gear teeth. In the same motion, the tape reel is centered within the data storage tape cartridge and a hub engagement member is lifted off of a flange of the tape reel.
