<p>A data recording disk file is provided with fixed block address head positioning information that is readable off-track with no increase in error rate. The positioning information includes both identification information 304 to provide radial and/or circumferential orientation for the recording head, and error handling information 305 to ensure that the id information is properly read. Either or both of the id information and the error handling information A, B, C for adjacent tracks are placed on the data storage disk at circumferentially offset positions to eliminate adjacent track interference, and at radially overlapped positions extending into the adjacent tracks to provide full readability when the head is off-track. <IMAGE></p> |
