Abstract
A servo pattern recording method according to an embodiment of the present technology is a method of recording a servo pattern in a plurality of servo bands arrayed at intervals in a width direction of a magnetic layer of a magnetic tape, including: causing the magnetic tape to travel with a predetermined tension; and recording a servo pattern in the plurality of servo bands at a second pitch narrower than a first pitch that is an arrangement interval of two servo read heads in a tape drive device that records data in the magnetic layer or reproduces data recorded in the magnetic layer.

A servo pattern recording method of recording a servo pattern in a plurality of servo bands arrayed at intervals in a width direction of a magnetic layer of a magnetic tape, comprising:
- causing the magnetic tape to travel with a predetermined tension;
- and
- recording a servo pattern in the plurality of servo bands, over the magnetic tape between a beginning of tape and an end of tape, at a second pitch narrower than a first pitch that is an arrangement interval of two servo read heads in a tape drive device that records data in the magnetic layer or reproduces data recorded in the magnetic layer.
A servo pattern recording apparatus that records a servo pattern in a plurality of servo bands arrayed at intervals in a width direction of a magnetic layer of a magnetic tape, comprising:
- a servo write head that includes a plurality of recording units arranged corresponding to the plurality of servo bands,
- each of the plurality of recording units including a magnetic gap for recording a servo pattern in the plurality of servo bands, over the magnetic tape between a beginning of tape and an end of tape, at a second pitch narrower than a first pitch that is an arrangement interval of two servo read heads in a tape drive device that records data in the magnetic layer or reproduces data recorded in the magnetic layer.
A method of producing a magnetic tape that includes a magnetic layer including a plurality of servo bands arrayed at intervals in a width direction, comprising:
- causing the magnetic tape to travel with a predetermined tension;
- and
- recording a servo pattern in the plurality of servo bands, over the magnetic tape between a beginning of tape and an end of tape, at a second pitch narrower than a first pitch that is an arrangement interval of two servo read heads in a tape drive device that records data in the magnetic layer or reproduces data recorded in the magnetic layer.
A magnetic tape, comprising:
- a magnetic layer that includes a plurality of servo bands, over the magnetic tape between a beginning of tape and an end of tape, arrayed at intervals in a width direction,
- the magnetic layer at least partially having a region in which a servo band pitch that is a distance between two adjacent servo bands is narrower than an arrangement interval of two servo read heads in a tape drive device that records information in the magnetic layer or reproduces information recorded in the magnetic layer.
A tape cartridge, comprising:
- a cartridge case;
- a tape reel that is rotatably housed inside the cartridge case;
- and
- a magnetic tape wound around the tape reel,
- the magnetic tape including a magnetic layer in which a plurality of servo patterns recorded, over the magnetic tape between a beginning of tape and an end of tape, at intervals in a tape width direction is recorded,
- the magnetic layer having
- a first region in which a servo band pitch that is a distance between two adjacent servo bands is narrower than an arrangement interval of two servo read heads in a tape drive device that records information in the magnetic layer or reproduces information recorded in the magnetic layer, and
- a second region in which the servo band pitch is wider than the arrangement interval of the two servo read heads.
