A cartridge is provided and includes tape-shaped magnetic recording medium; and cartridge memory; wherein cartridge memory includes communication unit that communicates with recording/reproducing device in state where cartridge is loaded on recording/reproducing device; storage unit; and control unit that stores, reads, and transmits information, wherein information includes manufacturing information of cartridge and adjustment information for adjusting a tension applied to the tape-shaped magnetic recording medium in a longitudinal direction of tape-shaped magnetic recording medium thereof, tape-shaped magnetic recording medium has a plurality of servo bands, and wherein a temperature expansion coefficient α of the tape-shaped magnetic recording medium satisfies 6 ppm/° C.≤α≤8 ppm/° C.

An issue facing shared read/write player hard disc drives (HDDs) is when a head-media contact event occurs, any resulting plume of debris caused by the contact event not only affects the magnetic disc currently being read or written, but other magnetic discs within the HDD enclosure. The presently disclosed technology is directed as mitigating the potential consequences of such a head-media contact event. By providing one or more internal access doors within the HDD, a magnetic disc currently being read from or written to may be physically isolated from other magnetic discs within the HDD. As a result, in the event of a head-media contact event, any resulting plume of debris caused by the contact event only affects the magnetic disc currently being read or written. The remaining magnetic discs within the HDD are isolated from the plume of debris.

A mover replacement system for removing a media mover, movable between an operating position and a removable position, from within a media library includes a module housing and a service tray. The module housing forms at least a part of a library housing. The service tray is removably positionable within the module housing. The service tray is configured to releasably retain the media mover when the media mover is in the removable position so that the service tray and the media mover are movable as an integral unit out of and into the module housing. The service tray includes a tray body and at least one locking mechanism that is movable relative to the tray body between a retracted position when the at least one locking mechanism is positioned not to engage the media mover, and a fully extended position when the at least one locking mechanism is positioned to retain the media mover relative to the tray body.

A magnetic recording medium is provided and includes a substrate; and a magnetic layer provided over the substrate, wherein (wmax−wmin)/wmin≤400 [ppm] . . . (1) where wmax and wmin are respectively maximum and minimum of average values of width corresponding to samples of magnetic recording medium measured after the samples are stored for two hours under storage conditions (a loading tension in the longitudinal direction of the magnetic recording medium, a temperature and a relative humidity) for each of the samples, and a width of a sample of the magnetic recording medium at 25° C. and 50% relative humidity and without loading is ½ inch, magnetic recording medium has Young's modulus of less than 8.0 GPa in a longitudinal direction, and 4.0≤TB/(TA−TB) . . . (2) where TA is average thickness of magnetic recording medium and TB is average thickness of substrate.

A vinyl record storage device features separate pockets for isolated storage of the vinyl record and its associated outer jacket. The jacket-holding pocket features a selectively openable and recloseable closure normally kept in a closed position, even during insertion and removal of the record to and from the other pocket, to maintain the jacket in pristine condition.

A disc library storage system and a disc cartridge thereof are provided. The disc library storage system includes a disc library, a disc drive tower, a disc transport device and a disc changing device. The disc library accommodates multiple discs. The disc drive tower accommodates multiple disc drives. The disc drives read data of the discs. The disc transport device moves the discs from the disc library to the disc drive tower and to the disc library. The disc changing device places a disc cartridge including an outer casing and a disc tray. The disc tray accommodates at least one replacement disc. The disc changing device has a pull-out state, in which the disc tray is received in the outer casing, and a close state, in which the disc tray is drawn from the outer casing and the disc transport device unloads the replacement disc from the disc tray.

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.

A load/unload ramp includes a body with ramps, load/unload surfaces, and a vertical wall. The ramps include outer grooves positioned between the ramps. The load/unload surfaces extend from the respective ramps. The vertical wall includes channels extending through the vertical wall. In embodiments, the channels are positioned between the load/unload surfaces.

A cartridge includes a tape-shaped magnetic recording medium and a cartridge memory. The cartridge memory includes a communication unit that communicates with a recording/reproducing device in a state where the cartridge is loaded on the recording/reproducing device; a storage unit; and a control unit that stores information received from the recording/reproducing device through the communication unit in the storage unit, reads the information from the storage unit according to a request from the recording/reproducing device, and transmits the information to the recording/reproducing device through the communication unit. The information includes manufacturing information of the cartridge and adjustment information for adjusting a tension applied to the magnetic recording medium in a longitudinal direction thereof, and the tape-shaped magnetic recording medium has a plurality of servo bands.

A magnetic recording medium is provided and includes a substrate; and a magnetic layer provided over the substrate, wherein (wmax−wmin)/wmin≤400 [ppm] . . .
