ABSTRACT:
A hard-disk storage apparatus is provided with a plurality of stacked magnetic recording disks each of which is provided with a plurality of tracks. Each of the tracks is specified by a cylinder address and a physical data-head address. Logical data-head addresses applied to the hard-disk are converted into the corresponding physical data-head address according to a conversion table pre-recorded within a non-volatile memory. Further, offset parameters of each data-head over two selected cylinders at predetermined temperatures are previously stored within the non-volatile memory. A microprocessor unit calculates offset parameters of all the data-heads over each of the tracks at a given temperature preferably measured within the hard-disk storage assembly. These offset parameters are utilized to correct the displacement of each data-head over a given track due to temperatures.
