Abstract

The present invention discloses a method of controlling rotating speed of an optical drive. After a plurality of reading requests are issued by a host, the rotating speed of a spindle motor is increased if the time interval between any two reading requests is less than a first time period and the total duration time of issuing these reading requests is more than a second time period.

Claims (7)

1. A method of controlling rotating speed of an optical drive, comprising steps of:

receiving a plurality of reading requests issued by a host; and

increasing the rotating speed of a spindle motor if the time interval between any two reading requests is less than a first time period and the total duration time of issuing these reading requests by the host is more than a second time period.

2. The method of controlling rotating speed of an optical drive according to claim 1 , wherein the first time period is 100 ms.

3. The method of controlling rotating speed of an optical drive according to claim 1 , wherein the second time period is 2.56 seconds.

4. The method of controlling rotating speed of an optical drive according to claim 1 , wherein the host is a personal computer.

5. The method of controlling rotating speed of an optical drive according to claim 1 , wherein the data addresses of these reading requests are discontinuous.
