Abstract
A magnetic disk drive device includes a rotatable disk. The disk has at least data tracks and guard band tracks. The data is previously recorded on the data tracks in the reversed magnetization form, whereas no data is recorded on the guard band track. While the magnetic head seeks the data from the tracks, the data is detected at first from the data track. This position where the first data is detected is recognized as a zero track. The magnetic head data seeking is performed based upon this zero track which is electronically detectable.
