Abstract:
1. A method for controlling a data access rate of an optical disc player utilizing a micro-controller to control data access rate, comprising: computing a plurality of command gaps of instructions received from a host, calculating an average value of the command gaps; comparing the average value with a judging value, said comparing including: comparing the plurality of command gaps against a threshold to identify a total number of times the command gaps are lesser than the threshold during a predetermined cycle; identifying that the received instructions indicate a play operation when the average value is greater than the judging value, said identifying including comparing the total number of times with the judging value and identifying that the received instructions indicate the play operation when the total number of times is greater than the judging value; otherwise, identifying that the received instructions indicate an extraction operation; and controlling a spindle motor and a pick-up head at a specific data access rate based on the identified operation.
