The present disclosure generally relates to a voice coil motor (VCM) yoke for a data storage device. The VCM yoke has a unitary body turned back on itself at opposite ends to form a “C” shape. The unitary body is electrically conductive. The body has a substantially flat inner surface upon which the coil is disposed. The unitary body also has a substantially flat top and a substantially flat bottom surface. A coil is disposed within the turns of the unitary body. The VCM yoke can be coupled to an actuator block using one or more fastening mechanisms that extend through openings in the VCM yoke.

SIGNAL PROCESSING DEVICE, MAGNETIC TAPE CARTRIDGE, MAGNETIC TAPE READING APPARATUS, PROCESSING METHOD OF SIGNAL PROCESSING DEVICE, OPERATION METHOD OF MAGNETIC TAPE READING APPARATUS, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM

A signal processing device includes a receiver that receives a plurality of playback signal sequence obtained by digitizing a plurality of reading results by a plurality of A/D converter, the plurality of reading results being obtained by reading data by a plurality of reading elements from a magnetic tape and a plurality of equalizers that perform waveform equalization of the plurality of playback signal sequence. The plurality of equalizers perform the waveform equalization by using a plurality of non-linear filters that have been learned to reduce distortion that occurs non-linearly in the plurality of playback signal sequence according to a condition under an environment in which the data is read from the magnetic tape. The plurality of non-linear filters being optimized to a suitable characteristic for the plurality of reading elements by optimization based on the plurality of reading results.

Head Positioning Assembly For Tape Embedded Drive
20210398558 · 2021-12-23 ·

The present disclosure generally relates to a head positioning assembly in a tape embedded drive. The tape embedded drive has two reels as well as four guide rollers. The reels and guide rollers are arranged within the tape embedded drive so as to position the head positioning assembly as close to the center of the tape embedded drive as possible. In so doing, the reels, guide rollers, and head assembly are more stable which reduces or even eliminates shock and vibration to the tape embedded drive.
