International Classification:

G11B 15/68
G11B 7/085

US Classification:

360 92, 369 3027

Abstract:

Disclosed are methods and apparatuses for transferring storage media between storage units comprising an expandable multi-unit storage system. The expandable storage apparatus comprises a first and second storage unit comprising media support locations. The support locations are capable of supporting at least one storage media element. At least one storage device is adapted to store and retrieve data to and from the storage media element associated with at least one of the storage units. At least one robotic system is associated with each of the storage units. A media pass-through transfer device is substantially disposed in the first storage unit and is adapted to transfer the storage element between the first and second storage units wherein the media pass-through transfer device is capable of temporarily extending into the second storage unit. The robotic system is capable of transferring the storage media element between at least the support locations, the storage device and the media pass-through transfer device.

International Classification:

G06G 7/12
G06G 7/16

US Classification:

327362

Abstract:

In one embodiment, a current sensing circuit corrects for the transient and steady state temperature measurement errors due to physical separation between a resistive sense element and a temperature sensor. The sense element has a temperature coefficient of resistance. The voltage across the sense element and a temperature signal from the temperature sensor are received by processing circuitry. The processing circuitry determines a power dissipated by the sense element, which may be instantaneous or average power, and determines an increased temperature of the sense element. The resistance of the sense element is changed by the increased temperature, and this derived resistance Rs is used to calculate the current through the sense element using the equation I=V/R or other related equation. The process is iterative to continuously improve accuracy and update the current.

Assignee:

Sony Corporation - Tokyo
Sony Electronics, Inc. - Park Ridge NJ

International Classification:

G11B 1722

US Classification:

369178

Abstract:

A disk cartridge engagement system having a carriage disposed within a sleeve for movement in the longitudinal direction, gripper arms pivotally mounted to the carriage for engaging a disk cartridge positioned distally of the sleeve, and a pair of biasing springs movable between first and second biasing conditions which correspond to gripping and releasing of the cartridge, respectively. The carriage includes a first cartridge receiving position in which the gripping arms are positioned to engage with a cartridge advanced onto the end of the base by a first distance, and a second cartridge receiving position in which the gripping arms are positioned to engage with a cartridge advanced onto the end of the base by a second distance which is shorter than the first. Thus, the gripping apparatus is capable of receiving disks ejected from apparatuses such as disk drives which can push ejected cartridges short distances as well as from those which can push ejected cartridges relatively longer distances.
