PURPOSE:To decrease damaging to a magnetic disc surface caused by the repetitive operation of rotation start and stop, by providing a pluraity of scanning tracks, per one slider surface, on the disc surface on which the slider surface of a manetic head contacts and runs. CONSTITUTION:In a magnetic disc device using the contact start stop system, a plurality of, e.g., two each tracks 12a, 13a and 12b, 13b on slider surfaces 60a and 60b are provided at both sides of a recording and reproducing gap section 60c of a run track on a disc surface 10, and the position corresponding to each running track is sequentially change with the operation of a stopper control mechanism on the slider surfaces 60a and 60b. That is, when the slider surfaces 60a and 60b correspond to the running tracks 12a and 12b at a time, since the slider surfaces 60a and 60b correspond to the running tracks 13a and 13b at the next CSS, the number of times of contact running is decreased and damaging to the disc surface can be decreased. |
