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.

One embodiment provides a system comprising a motor and a disc selector mechanism. The disc selector mechanism is coupled to a bottom of a guide cage and maintained in a space below the cage. The disc selector mechanism comprises a shaft, transmission components, and a slide assembly that is laterally slidable along the shaft in response to the motor driving the transmission components. The slide assembly comprises a slide coupled to the shaft, a pivot bar coupled to the slide, and pick blades pivotally coupled to the pivot bar. A linear motion of the slide assembly along the shaft drives a linear translation of the pivot bar. The linear translation drives a pick blade of the slide assembly to move towards a side of the cage and out of the space and to pivot to a raised position to contact and lift a disc upwards into a disc gripper device.

A data recording apparatus including: a data reading device configured to read data from a first recording medium and configured to store data and first management data for managing the data by file; a data recording device configured to record data on a second recording medium; a management data producing device configured to produce second management data for managing data recorded on the second recording medium based on the first management data of the first recording medium on which the data recorded on the second recording medium has been recorded; a data determining device configured to determine data unrecorded on the second recording medium by comparing the first management data read by the data reading device from the first recording medium with the second management data recorded on the second recording medium; a control device configured to read the data determined by the data determining device from the first recording medium and cause the recording device to record the read data onto the second recording medium; and a display device configured to display the recording status of data, managed by the first management data read by the reading device from the first recording medium, on the second recording medium, wherein the recording status includes one of recording of data complete, recording of data in progress, and recording of data yet to begin.

A ring-shaped glass spacer is to be arranged in contact with a magnetic disk in a hard disk drive device. A film that contains at least one of tin oxide, zinc oxide, and titanium oxide is formed on each surface of a main surface, and an outer circumferential edge surface, and an inner circumferential edge surface of the glass spacer. The thickness of the film on a center portion of the outer circumferential edge surface of the glass spacer is larger than the thickness of the film on a center portion of the inner circumferential edge surface of the glass spacer.

A package includes a plurality of accommodation regions where a plurality of holders are accommodated in such a manner that the plurality of holders are able to be put in and out, and a partition structure that divides the plurality of accommodation regions. Each holder holds a plurality of magnetic tape cartridges in such a manner that the plurality of magnetic tape cartridges are able to be put in and out of the holder. In a state in which the holder is accommodated in the accommodation region, a height of the partition structure is higher than a height of the holder.

A data storage cartridge according to one embodiment comprises a housing configured to house a data storage medium, a sensor coupled to the housing, and a microcontroller coupled to the sensor. The microcontroller is configured to wirelessly communicate information about the sensor. Other embodiments relate to a data storage cartridge comprising a housing configured to house a data storage medium, a cartridge memory coupled to the housing, the cartridge memory having a wireless communications interface, and a microcontroller in physical communication with the cartridge memory. The microcontroller is configured to wirelessly communicate information retrieved from the cartridge memory. Additional embodiments relate to a data storage cartridge comprising a mechanical write protect mechanism coupled to the housing of the data storage cartridge, an actuator coupled to the mechanical write protect mechanism for selectively changing a state of the mechanical write protect mechanism, and a microcontroller configured to control the actuator.

A base member is structured to define a portion of a casing in which a gas with a density lower than that of air is to be sealed and to support a motor to be housed in the casing. The base member includes a base body made of a cast material, an information mark, and an insulating coating layer. The information mark includes casting information and is located on a portion of a surface of the base body. The insulating coating layer is defined on the surface of the base body and covers the information mark.
