Abstract
In one embodiment, a tape reel includes a hub and spaced apart opposing flanges extending out from the hub such that a tape may pass between inner surfaces of the flanges and wrap around the hub. The flanges have a cross section in which a rate at which a distance between the inner surfaces of the flanges increases is greater nearer to the hub and lesser farther from the hub.
Claims21
A tape reel, comprising:
- a hub;
- a first flange having a first surface extending out from the hub;
- a second flange having a second surface extending out from the hub opposite the first surface;
- the first surface tapering away from the second surface at a first rate nearer to the hub and at a second rate lesser than the first rate farther from the hub.
A tape reel, comprising:
- a hub;
- and
- spaced apart opposing flanges extending out from the hub such that a tape may pass between inner surfaces of the flanges and wrap around the hub, the flanges having a cross section in which a rate of increase of a distance between the inner surfaces of the flanges is greater nearer to the hub and lesser farther from the hub.
A tape reel having an axis of rotation, the tape reel comprising a first surface extending away from the axis of rotation and a second surface extending away from the axis of rotation, the first and second surfaces facing one another and diverging away from one another at a greater rate nearer to the axis of rotation and at a lesser rate farther from the axis of rotation.
A tape reel having an axis of rotation, the tape reel comprising a first surface extending away from the axis of rotation and a second surface extending away from the axis of rotation, the first and second surfaces facing one another and diverging such that an angle θ at which an edge of a tape intersects the first surface or the second surface is larger where an angle φ between an actual tape path and a desired tape path is smaller and the angle θ is smaller where the angle φ is larger.
A tape cartridge, comprising:
- a housing;
- a reel rotatably supported in the housing, the reel including a hub and spaced apart opposing flanges extending out from the hub such that a tape may pass between inner surfaces of the flanges and wrap around the hub, the flanges having a cross section in which a rate of increase of a distance between the inner surfaces of the flanges is greater nearer to the hub and lesser farther from the hub;
- and
- a tape drive interface operatively connected to the reel for rotating the reel at the urging of a drive mechanism.
A tape cartridge, comprising:
- a housing;
- a reel rotatably supported in the housing, the reel having an axis of rotation and the reel including a first and second surfaces extending away from the axis of rotation, the first surface and the second surface facing one another and diverging away from one another at a greater rate nearer to the axis of rotation and at a lesser rate farther from the axis of rotation;
- and
- a tape drive interface operatively connected to the reel for rotating the reel about the axis at the urging of a drive mechanism.
A tape drive, comprising:
- a tape cartridge loading mechanism;
- a take-up reel including a hub and spaced apart opposing flanges extending out from the hub such that a tape may pass between inner surfaces of the flanges and wrap around the hub, the flanges having a cross section in which a rate of increase of a distance between the inner surfaces of the flanges is greater nearer to the hub and lesser farther from the hub;
- a head;
- an actuator having a carriage carrying the head;
- and
- an electronic controller configured to receive read and record instructions and data from a computer or other host device and to control operation of the loading mechanism, the take-up reel, the actuator and the head.
