A system, according to one embodiment, includes: a plurality of tape reels; and a tape drive configured for reading data from tape stored on at least one of the plurality of tape reels. At least some of the tape reels have a tape wound thereon and a spring-like clip coupled to a free end of the tape. Moreover, the clip is selectively positionable in a wrapped position where the clip wraps around a portion of the tape when the tape is wound onto the reel, thereby holding the portion of the tape in place on the reel.

Spring clip leader and housing for magnetic tape

A disc cassette includes a curved portion. The curved portion includes multiple ribs that define multiple disc slots. The disc slots are configured to hold multiple discs that are spaced apart by the ribs. The disc cassette further includes multiple index features positioned on an inside edge of the curved portion. The index features are configured to allow alignment of a kicker device of a disc retrieval unit (DRU) to a disc of the disc cassette to lift the disc into a disc gripper device without disturbing one or more other discs of the disc cassette that are adjacent to the disc.

Disc storage cassettes comprising index features

A disc cassette includes a curved portion configured to hold multiple discs. The disc cassette further includes a bottom side including track connectors configured to position the disc cassette relative to one or more track portions that hold the disc cassette in place. The disc cassette is slideable along the one or more track portions.

Disc storage cassettes comprising track connectors

Various embodiments relate to methods for loading and unloading a tape storage medium. According to one embodiment, a method for loading a tape storage medium includes positioning a mechanized take-up reel with respect to a tape supply reel, positioning a feature coupled to a tape storage medium on the tape supply reel with respect to the mechanized take-up reel, rotatably decoupling an inner hub of the mechanized take-up reel from an outer hub of the mechanized take-up reel, extending a tongue of the mechanized take-up reel, engaging the tongue with the feature, retracting the tongue and feature into the outer hub, and nonrotably coupling the inner hub with the outer hub.

A disc cassette includes a curved portion configured to hold multiple discs. A platform portion abuts the curved portion. A movable bale is configured to maintain discs securely in the disc cassette except when rotated off the discs.

Disc storage cassettes comprising a movable bale

An apparatus includes a first jaw device, a second jaw device, and a disc sensor configured to sense presence of a storage disc between the first jaw device and the second jaw device. The first jaw device and the second jaw device form a gripper device configured to clamp a particular portion of a storage disc including an arc segment along an outer edge of adjacent surfaces of the storage disc.

Disc gripper for storage disc

A method and apparatus is provided to enable loading and/or unloading of a storage drive. The body has a first end, a second end, and a path extending from the first end to the second end. The body is configured to receive the computer readable storage device and maintain the computer readable storage device in a first position. The body is configured to passively change orientation from a first orientation to a second orientation responsive to contact from the computer readable storage device. The first orientation maintains the first position of the computer readable storage drive and the second orientation facilitates traversal of the computer readable storage device along the path.

Optical disk drive guide

A spring-like clip for a spool of tape, one end of the clip being attached to one end of the tape, and another end of the clip having an engagement feature that allows the clip to be pulled from the spool. The clip is configured to curve around the spool to hold the tape in place. In one general embodiment, a product includes a reel, a tape coupled to the reel, and a spring-like clip coupled to a free end of the tape. The clip is selectively positionable in a wrapped position where the clip wraps around a portion of the tape when the tape is wound onto the reel, thereby holding the portion of the tape in place on the reel. Systems for using various types of such products are presented, and generally include a tape drive configured for reading data from tape stored on such products.

A disc cassette includes a curved portion configured to hold multiple discs. A platform portion abuts the curved portion. A movable bale is configured to maintain discs securely in the disc cassette.

Disc storage cassettes

Various embodiments relate to apparatuses and methods for loading and unloading a tape storage medium. In one embodiment, an apparatus for such purpose includes a mechanized take-up reel. The mechanized take-up reel includes an inner hub, an outer hub being selectively nonrotatably coupleable with the inner hub (where at least one of the hubs is coupled to a rotating mechanism), a tongue coupled to the inner hub, and a slot in the outer hub for permitting the tongue to extend beyond a periphery of a tape engaging surface of the outer hub upon relative rotation between the inner and outer hubs.

An apparatus includes one or more disc media cassettes configured to store multiple disc-based media. Multiple disc drives are configured to read and write data to the multiple disc-based media. A robotic delivery device is configured to transport a selected disc-based media to and from at least one disc drive of the multiple disc drives, and to transport the selected disc-based media directly to a spindle on the at least one disc drive.

High performance robotic optical storage system

An optical disc drive includes a spindle connected to an optical assembly. A disc clamp device is configured to hold an optical disc on the spindle. A contiguous opening on at least two adjacent sides in a plane of a disc mount position intersect at a common corner of the optical disc drive.

Optical disc drive

An apparatus includes a motor configured to drive a driving element within a housing. A caliper is connected to the housing and configured to force a first jaw device toward a second jaw device based on movement of the driving element. A disc sensor is configured to sense presence of a storage disc and to limit insertion travel of a storage disc between the first jaw device and the second jaw device. The first jaw device and the second jaw device form a gripper device configured to clamp a particular portion of a storage disc.

Disc gripper for storage discs

A disc cassette includes a curved portion configured to hold multiple discs and a platform portion abuts the curved portion. The platform portion and the curved portion each include multiple rib pairs configured to separate adjacent discs from touching one another, and to form a disc slot between each rib pair. Disc slots of the platform portion of the disc cassette are configured to provide a guide for disc removal from the disc cassette.

A contact magnetic transfer (CMT) master template has a flexible plastic film with a planarized top or upper surface containing magnetic islands separated from one another by nonmagnetic regions. The flexible plastic film is secured at its perimeter to a silicon annulus that provides rigid support at the perimeter of the film. The plastic film is preferably polyimide that has recesses filled with the magnetic material that form the pattern of magnetic islands. The upper surfaces of the islands and the upper surfaces of the nonmagnetic regions form a continuous planar surface. The nonmagnetic regions are formed of chemical-mechanical-polishing (CMP) stop layer material that remains after a CMP process has planarized the upper surface of the plastic film.
