Abstract
A magnetic recording apparatus according to the present invention comprises a magnetic recording medium having a plurality of servo sectors and a plurality of data sectors on the tracks, first sensing means for sensing a first servo sector located before a target data sector and, on the basis of the first servo sector, sensing the target data sector, judging means for judging whether or not the first sensing means has sensed the first servo sector, and second sensing means for sensing the target data sector on the basis of a second servo sector different from the first servo sector, in response to the judging means judging that the first sensing means has failed to sense the first servo sector.
