Embodiments for passive retraction of a hub clamp in an optical disc drive. The optical disc drive may comprise a spindle hub coupled to an optical assembly. The optical disc drive may further include a disc clamp assembly configured to hold an optical disc on the spindle hub, the disc clamp assembly including a hub clamp partially comprised within a clamp carriage. The hub clamp of the optical disc drive may be biasedly drawn toward the spindle hub when in a first position and biasedly drawn toward the clamp carriage when in a second position. The bias may be generated by at least one ferromagnetic material integrated into the hub clamp and at least one ferromagnetic material integrated into the spindle hub.

A calibration system includes a moveable arm configured for movement within an optical disc storage system. A disc kicker device includes a stop portion, an actuator and an actuator tip that contacts an optical disc. The disc kicker device is connected to the moveable arm. The calibration system: determines an operation state based on a stop position for the actuator tip in response to an applied torque to the disc kicker device, and performs alignment of the actuator tip with the optical disc.

Actuator tip calibration for robotic optical storage system

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 calibration system includes a moveable arm configured for movement within an optical disc storage system. A disc kicker device includes an actuator and an actuator tip that contacts an optical disc. The disc kicker device is connected to the moveable arm. The calibration system performs a calibration operation to calibrate the actuator at the actuator tip to correct displacement error.

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

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.

Embodiments relate a universal serial bus (USB) filter hub. An aspect includes receiving, by the USB filter hub that is in communication with a host computer system, a connection from a USB device at a USB port of the USB filter hub. Another aspect includes determining, by the USB filter hub, a type of the USB device. Another aspect includes determining whether the type of the USB device is valid. Yet another aspect includes, based on determining that the type of the USB device is valid, filtering commands that are communicated between the USB device and the host computer system via the USB filter hub based on a predetermined command set corresponding to the determined type of the USB device.

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

Supporting of both reading and writing data to a storage media is provided. A data request is received and a storage medium to support the data request is identified. A parameter related to the data request is retrieved and pre-loaded to an associated media accessor prior to loading the storage media. The parameter includes a setting adjustment of the media accessor in support of the data request. The media accessor performs the data request in compliance with the setting adjustment.

Pre-loading a parameter to a media accessor to support a data request

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.

Embodiments relate to data storage media, and reading data from the media and writing data to the media. A data structure is provided to identify storage location and/or media parameters. One or more parameters of storage media is pre-loaded and conveyed to an associated media accessor prior to transferring data across the storage media in support of an associated read or write request.

Random read performance of optical media library

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.
