METHOD FOR HANDLING INTERRUPT REQUEST IN OPTICAL STORAGE DRIVE
First Claim
1. A method for handling an interrupt request in an optical storage drive when the optical storage drive executes a control procedure or operation, the method comprising:
- utilizing the optical storage drive to receive an interrupt request from a control circuit;
checking whether the interrupt request is a read command;
if the interrupt request is a read command, checking whether data indicated by the read command is stored in a buffer; and
if the indicated data is stored in the buffer, transferring the corresponding data to the control circuit from the buffer to respond to the interrupt request.

Abstract
When an optical storage drive executes a control procedure or operation, a method of handling an interrupt request includes utilizing the optical storage drive to receive an interrupt request from a control circuit; checking whether the interrupt request is a read command; if the interrupt request is a read command, checking whether data indicated by the read command is in a buffer; and if the indicated data in the buffer, transferring the corresponding data to the control circuit from the buffer to respond to the interrupt request.
