Abstract
A data storage tape cartridge has a housing (12) and a tape reel assembly (14) rotatably mounted in the housing (12). An unlocking member (170) is constructed from a filled thermoplastic and a wear member (185) is operatively connected to the unlocking member (170) forming a wear surface.
Claims9
A data storage cartridge comprising:
- a) a housing defining an enclosure;
- b) a tape reel assembly rotatably mounted in the housing;
- c) a brake member operatively connected to the housing;
- d) an unlocking member operatively connected to the tape reel assembly and moveable between a locked position and an unlocked position;
- wherein when in the unlocked position, the unlocking member moves the brake member away from the tape reel, thereby allowing the tape reel to rotate;
- e) the unlocking member constructed from a filled polycarbonate;
- and
- f) a wear member operatively connected to the unlocking member forming a wear surface at a position which contacts the brake member when in the unlocked position, the wear member being a polyethylene planar disk film.
