Abstract:
1. A storage apparatus comprising: a storage medium with a configuration of having a plurality of tracks formed of a magnetic-storable magnetic substance, the tracks being sectioned by a non-magnetic substance that does not allow magnetic recording; a head having a read head for reading magnetic storage information recorded on the tracks and a write head for writing magnetic storage information on the tracks; a measurement data recording unit that causes the head to move across a predetermined amount at least equal to or more than one track during one lap of track, with a predetermined radial position and a track position of the storage medium being taken as a recoding start point, thereby writing measurement data in the storage medium while drawing a spiral path; a measurement data reading unit that causes the head to move, while scanning read-beginning points within a predetermined scanning range from an inner perimeter side including the recording start point of the measurement data recording unit to an outer perimeter side, across the predetermined amount of the measurement data recording unit for each of the read-beginning points, thereby reading the measurement data from the storage medium while drawing a spiral path; and
