Patent ID: 7593179

Claim:
A control apparatus for controlling a storage device, said storage device performing writing processing to write data into a storage medium by a head, said control apparatus comprising: a processor to control the control apparatus according to a process including: detecting positional information of the head every predetermined time interval, determining whether the positional information is not greater than a position threshold; computing next-sample projected positional information of the head on the basis of the positional information detected current time and difference between the positional information detected previous time and the positional information detected current time upon determining the positional information being not greater than the position threshold; determining whether the computed next-sample projected positional information is greater than next-sample projected position threshold; and controlling the storage device to stop the writing processing after writing processing is performed to the end of the sector, upon determining the next-sample projected positional information being greater than the next-sample projected position threshold.
