Abstract
A servo pattern recording apparatus according to an embodiment of the present technology is an apparatus that records a plurality of servo patterns adjacent to each other in a tape width direction on a magnetic layer of a magnetic tape, including: a servo write head; and a temperature adjustment unit. The servo write head includes a plurality of recording units arranged corresponding to a plurality of servo bands of the magnetic layer on which the plurality of servo patterns is recorded. The temperature adjustment unit is configured to be capable of individually adjusting temperatures of the plurality of recording units.

An apparatus that records a plurality of servo patterns adjacent to each other in a tape width direction on a magnetic layer of a magnetic tape, comprising:
- a servo write head that includes a plurality of recording units arranged corresponding to a plurality of servo bands of the magnetic layer on which the plurality of servo patterns is recorded;
- and
- a temperature adjustment unit that is configured to be capable of individually adjusting temperatures of the plurality of recording units.
A method of recording a plurality of servo patterns adjacent to each other in a tape width direction on a magnetic layer of a magnetic tape, comprising:
- causing the magnetic tape to travel;
- individually adjusting temperatures of a plurality of recording units of a servo write head;
- and
- recording the plurality of servo patterns on the magnetic layer by the plurality of recording units.
A method of producing a magnetic tape in which a plurality of servo patterns adjacent to each other in a tape width direction is recorded on a magnetic layer of the magnetic tape, comprising:
- causing the magnetic tape to travel;
- individually adjusting temperatures of a plurality of recording units of a servo write head;
- and
- recording the plurality of servo patterns on the magnetic layer by the plurality of recording units.
A magnetic tape in which a plurality of servo patterns adjacent to each other in a tape width direction is recorded on a magnetic layer of the magnetic tape, wherein
- an average value of differences in a servo band pitch between two adjacent servo bands, of the plurality of servo bands, over an entire tape length, is 100 nm or less.
