An apparatus, according to one embodiment, includes: a support plate, a stator, a rotor sub-assembly, and at least one isolation mount coupled between the support plate and the stator. The isolation mount is for reducing transfer of vibration from the stator to the support plate. Moreover, the stator is coplanar with the support plate. The rotor sub-assembly includes a magnet, and a hub rotatably fixed relative to the magnet. The rotor sub-assembly is also configured to rotate relative to the support plate and the stator. Other systems, methods, and computer program products are described in additional embodiments.

A magnetic-tape storage apparatus having a simple structure and being able to surely store magnetic tapes on each of which valuable data are recorded and the recorded data on them at a low cost and over a long period in a small space, a magnetic-tape storage apparatus comprises a housing, a cartridge storage part, a magnetic tape drive, a cartridge transfer device [18] to selectively transfer a plurality of cartridges stored in the cartridge storage part to the magnetic tape drive and to return to the original position, a cartridge data reading device to selectively and contactlessly read data retained in each memory chip of the cartridges stored in the cartridge storage part and a computer to control them and to rewind the cartridges timely.

An apparatus, according to one embodiment, includes: a support plate; a stator; a stator support arm having a first end that is coupled to the support plate, the stator support arm extending from the support plate to the stator. The apparatus further includes at least one isolation mount coupled between a second end of the stator support arm and the stator for reducing transfer of vibration from the stator to the stator support arm; and a rotor sub-assembly. The rotor sub-assembly is configured to rotate relative to the support plate and the stator, the rotor sub-assembly including: a magnet; and a hub rotatably fixed relative to the magnet.

A metallic plate that is a structure of a release member, the release member being configured to be integrally rotatable with a reel accommodated in a case, and the release member moving a locking member from a locking position, at which the locking member locks rotation of the reel relative to the case, to an allowing position, at which the locking member allows rotation of the reel. The metallic plate comprises a touching surface that is to be touched by a distal end of a sliding protrusion portion that protrudes from the locking member; and a structure such that, if a plurality of the metallic plate are stacked in a plate thickness direction in a state in which the metallic plates are not attached to release members, the touching surface of each metallic plate is not in contact with any other of the metallic plates.

A drive-implemented method according to one embodiment includes determining that unthreading of a tape is to be performed, and in response to the determination that the unthreading of the tape is to be performed, determining whether to write an index on the tape prior to unthreading the tape. In response to a determination to write the index on the tape, the index is written on the tape prior to unthreading the tape. The tape is then unthreaded. The drive-implemented method further includes receiving a write request after the unthreading, rethreading the tape, and writing data corresponding to the write request on the tape. The index stored on the tape prior to the unthreading is overwritten with the data corresponding to the write request.
