Abstract
The present disclosure generally relates to a tape drive comprising a tape head comprising one or more modules, wherein each module comprises a plurality of servo readers; a plurality of read elements; and a control circuitry configured to retrieve a priority servo reader designation for a bundle of data tracks of the plurality of data tracks, wherein the priority servo reader designation is one or more servo readers of the plurality of servo readers; use the designated priority servo reader to adjust a lateral position the tape head; retrieve a target delta Y position (ΔYpos); and adjust a tilt of the tape head based on the target ΔYpos.
Claims21
A tape drive, comprising:
- a tape head comprising one or more modules, each module comprising a plurality of read elements and a plurality of servo readers, wherein the plurality of read elements are configured to read a plurality of data tracks of a formatted tape;
- and
- a control circuitry configured to:
- retrieve a priority servo reader designation for a bundle of data tracks of the plurality of data tracks, wherein the priority servo reader designation is one or more servo readers of the plurality of servo readers, and wherein the priority servo reader designation is stored in at least one of a cartridge memory, a superblock preamble, one or more regions of the formatted tape, or a data storage device;
- use the designated priority servo reader to adjust a lateral position the tape head;
- retrieve a target delta Y position (ΔYpos);
- and
- adjust a tilt of the tape head based on the target ΔYpos.
A tape drive, comprising:
- a tape head comprising one or more modules, each module comprising a plurality of read elements and a plurality of servo readers, wherein the plurality of read elements are configured to read a plurality of data tracks of a formatted tape;
- and
- a control circuitry configured to:
- retrieve a first priority servo reader designation for a first bundle of data tracks of the plurality of data tracks,
- use the first designated priority servo reader to position the tape head for reading the first bundle of data tracks;
- retrieve a first target delta Y position (ΔYpos) of the first bundle of data tracks;
- adjust a tilt of the tape head based on the first target ΔYpos;
- control the plurality of read heads to read the first bundle of data tracks;
- retrieve a second priority servo reader designation for a second bundle of data tracks of the plurality of data tracks, wherein each of the first and the second priority servo reader designations is one or more servo readers of the plurality of servo readers;
- use the second designated priority servo reader to position the tape head for reading the second bundle of data tracks;
- retrieve a second target delta Y position (ΔYpos) of the second bundle of data tracks;
- adjust a tilt of the tape head based on the second target ΔYpos;
- and
- control the plurality of read heads to read the second bundle of data tracks.
A tape drive, comprising:
- a tape head comprising one or more modules, each module comprising a plurality of read elements and a plurality of servo readers, wherein the plurality of read elements are configured to read a plurality of data tracks of a formatted tape;
- means for retrieving a priority servo reader designation, wherein the priority servo designation is one or more servo readers of the plurality of servo readers;
- means for adjusting a lateral position of the tape head;
- means for retrieving a target delta Y position (ΔYpos);
- and
- means for adjusting a tilt of the tape head based on the target ΔYpos.
