Abstract:
A method for a disc drive, in data communication with a host, to optimally handle a write-time error, in which information obtained from a servo burst indicates that the disc drive's head was either off course or anticipated to head off course, comprising acts of:(a) validating the course and anticipated course of the head; (b) upon determining that the head was either off course or anticipated to go off course performing the following acts: (i) halting the disc writing operation in synchronization with the end of writing a sector, so that a sector is not left half-written; (ii) transferring information representing the sectors which were improperly written to the host; and (iii) incrementing a value, which represents the servo burst number to be detected, thereby inducing a condition wherein the disc drive will attempt to write immediately upon properly validating the next burst.
