摘要： Systems and methods that may be employed for mounting data storage drives (e.g., HDDs, SSDs, etc.) within a chassis of an information handling system using storage drive carrier retaining features of a chassis and mating securing features of a storage drive carrier to provide a tool-less storage drive carrier mounting solution for an information handling system chassis that accommodates both cost-effective tooled storage drive carrier and premium tool-less storage drive carrier mounting configurations, e.g., without additional investment or reconfiguration of the chassis for either type of mounting configuration. The disclosed systems and methods may be further so implemented in a manner that without the presence of one or more drive bays within the chassis interior that may restrict access to the chassis interior and which may require a larger chassis and chassis enclosure to contain bay/s.

摘要： A tape-type magnetic recording medium, includes a substrate; and a magnetic layer provided on the substrate. The magnetic recording medium is configured such that (1) (wmax−wmin)/wmin≤400 [ppm] where wmax and wmin are respectively maximum and minimum of average values of width of the magnetic recording medium measured under four environments whose temperature and relative humidity are (10° C., 10%), (10° C., 80%), (29° C., 80%), and (45° C., 10%), respectively, and the magnetic layer has a squareness ratio of 65% or more in the vertical direction, and (2) 4.4≤TB/(TA−TB) where TA is an average thickness of the magnetic recording medium and TB is an average thickness of the substrate.

摘要： The disc device comprises disc selector spindle that hold discs in a stacked state, separate lowermost disc from other discs, and supply separated lowermost disc to drive unit. The disc selector spindle includes first, second, and third support claws that move to storage position at which each support claw is stored inside center hole of disc and protrusion position at which each support claw protrudes in a region located in the vicinity of inner diameter of disc in plan view. First support claw moves to storage position and protrusion position independently of the movements of second support claw and third support claw. Second support claw is disposed so as to be shifted from third support claw in a stacking direction of disc by a thickness of one disc, and to move from storage position to protrusion position at a timing different from a timing of third support claw.

摘要： Apparatus for data storage in a cartridge library archival system. In some embodiments, a plurality of portable data storage cartridges are provided. Each cartridge has a sealed housing which encloses at least one head-disc interface (HDI) with a magnetic data transducer adjacent a rotatable data recording medium. An access station has control electronics configured to transfer data signals between a memory and the transducer of a selected cartridge loaded to the access station. The access station further has an external voice coil motor (VCM) configured to engage and advance the transducer of the selected cartridge across a recording surface of the medium. A transport mechanism can be used to automatically load the cartridges to the access station. Multiple cartridges can be loaded sequentially or concurrently to support various data transfer operations.
