Patent ID: 8134793

Claim:
A disk drive, comprising: a disk comprising a plurality of servo wedges; a head actuated over the disk; a read/write channel configured to read data from and write data to the disk using the head; a control processor configured to write data from a buffer to the disk via the read/write channel; and a servo system configured to read servo information from one of the servo wedges via the read/write channel when the head is positioned over the servo wedge, to generate first and second status information based on the read servo information, to output the first and second status information to the control processor, and to output first and second interrupt signals to the control processor, the first and second interrupt signals being spaced apart by a time delay; wherein, in response to the first interrupt signal, the control processor is configured to determine whether to release data from a host based on the first status information, and in response to the second interrupt signal, the control processor is configured to determine whether to release data from the host based on the second status information.
