Patent ID: 7196862

Claim:
A method of storing data segments in a rotatable storage media in a data storage device, comprising: storing a first data segment in first tracks in the storage media, wherein the first tracks include a first start track and a first end track, the first data segment starts in the first start track at a start rotational phase, ends in the first end track at an end rotational phase, starts in adjacent first tracks at start rotational phases offset by an intra-segment rotational skew angle and ends in adjacent first tracks at end rotational phases offset by the intra-segment rotational skew angle; and storing a second data segment in second tracks in the storage media, wherein the second tracks include a second start track and a second end track, the second data segment starts in the second start track at the start rotational phase, ends in the second end track at the end rotational phase, starts in adjacent second tracks at start rotational phases offset by the intra-segment rotational skew angle and ends in adjacent second tracks at end rotational phases offset by the intra-segment rotational skew angle; wherein the first and second data segments are radially coherent, the first end track is adjacent to the second start track, and the start and end rotational phases are offset by an inter-segment rotational skew angle that is greater than the intra-segment rotational skew angle.
