Abstract
(EN)
In a servo pattern recording method according to one embodiment of the present invention, a servo pattern is recorded on a tape-like magnetic recording medium comprising a magnetic layer having five or more servo bands, wherein: at least three first servo bands for recording first servo band identification information comprising multiple bits, and at least two second servo bands for recording second servo band identification information comprising multiple bits differing from the first servo band identification information, are determined; and the first servo band identification information and the second servo band identification information are recorded in the same phase in the first servo bands and the second servo bands, respectively.
