Servo pattern recording method, servo pattern recording apparatus, manufacturing method for a tape-like magnetic recording medium, and tapelike magnetic recording medium

A servo pattern recording apparatus that records a servo pattern on a tape-like magnetic recording medium including a magnetic layer including five or more servo bands, the apparatus comprising:

• a servo write head including a plurality of recording portions arranged corresponding to the servo bands;
• and
• a drive unit that
• outputs a first recording signal for recording the first servo band identification information with respect to a first recording portion corresponding to at least three first servo bands in which first servo band identification information constituted by a plurality of bits is to be recorded, and
• outputs a second recording signal for recording the second servo band identification information on a same phase as the first servo band identification information with respect to the second recording portion corresponding to at least two second servo bands in which second servo band identification information constituted by a plurality of bits is to be recorded, the second servo band identification being different from the first servo band identification information.

A manufacturing method for a tape-like magnetic recording medium including a magnetic layer including five or more servo bands, the method comprising:

• determining
• at least three first servo bands in which first servo band identification information constituted by a plurality of bits is to be recorded, and
• at least two second servo bands in which second servo band identification information constituted by a plurality of bits is to be recorded, the second servo band identification being different from the first servo band identification information;
• and
• recording each of the first servo band identification information and the second servo band identification information on a same phase in the first servo band and the second servo band.

A tape-like magnetic recording medium, comprising

• a magnetic layer including five or more servo bands, wherein
• the servo bands include
• at least three first servo bands in which first servo band identification information constituted by a plurality of bits is recorded, and
• at least two second servo bands in which second servo band identification information constituted by a plurality of bits is recorded, the second servo band identification information being different from the first servo band identification information,
• wherein the first servo band identification information and the second servo band identification information are recorded on a same phase.
