Abstract:
1. A disk formatter for a rotating storage medium, the disk formatter comprising: a target sector identification module configured to determine a block of target sectors of the rotating storage medium based on a read/write command signal; a current sector identification module configured to determine a current sector corresponding to a current position of a read/write head on a track of the rotating storage medium; a latency signal generator configured to determine a latency period from the current sector to begin a read/write operation on the track, wherein the latency period is equal to X sectors in length, where X is an integer; and a control module configured to begin the read/write operation at a command start sector based on the latency period, wherein the command start sector is (i) different than a first sector of the block of target sectors, (ii) located within the block of target sectors, (iii) on the track, and (iv) the X sectors away from the current sector, wherein the control module is configured to end the read/write operation on a sector that is rotationally positioned adjacent and prior to the command start sector, and wherein the control module is configured to end the read/write operation based on detection of the command start sector and subsequent to at least one of (i) reading from each of the target sectors or (ii) writing to each of the target sectors.
