Abstract
A disk drive is disclosed having a disk, a head actuated over the disk, a buffer memory for storing control routine op codes and control routine data, and a microprocessor for receiving the control routine op codes and control routine data. Control circuitry within the disk drive services an access request generated by the microprocessor by accessing the buffer memory, and monitors at least one interrupt. If the interrupt occurs while servicing the access request, the control circuitry enables the microprocessor to execute an interrupt service routine corresponding to the interrupt. Enabling the microprocessor to execute the interrupt service routine rather than wait for the access request reduces the latency in servicing the interrupt.
