According to one embodiment, a magnetic disk device includes a controller that disposes a plurality of conventional magnetic recording division regions and a plurality of shingled write magnetic recording division regions in the user data region, sets, when receiving a command to write data to a first LBA, a first conventional magnetic recording region to a first conventional magnetic recording division region, and sets, when receiving a command to write data to a second LBA, a first shingled write magnetic recording region to a first shingled write magnetic recording division region.

A storage device comprises tape reel(s) holding tape media for storing data, a head assembly, motor(s) configured to actuate the head assembly, a sealed casing, and a printed circuit board assembly (PCBA) configured to control operations of the motor(s). The head assembly comprises a support structure, a head bar with read head(s) and write head(s), and a suspension system connecting the head bar to the support structure. The sealed casing encloses in its interior the tape reel(s), the head assembly, and the motor(s). Meanwhile, the PCBA is mounted on an external surface of the casing.

A first heat-assisted magnetic recording (HAMR) writer writes to a surface of a magnetic disk using during an initial time period. A second HAMR writer is configured to write to the surface but not during the initial time period. The initial time period extends from a first time when the disk drive is first used to a second time when a near-field transducer of the first HAMR writer reaches a first wear threshold. During a subsequent time period after the initial time period, to the surface of the disk is written to using the second HAMR writer and not the first HAMR writer.

Disclosed here is a magnet for use in a motor. The magnet comprises a magnet body. The magnet body comprises a plurality of coated magnetic granules. Each coated magnetic granule of the plurality of coated magnetic granules comprises a magnetic granule and a metallic layer coating the magnetic granule.
