Abstract
A method to control the operating speed of computer storage device by determining the transmitting mode of a computer interface. A first speed transmitting mode is used to output a controlling signal to the exterior interface when the transforming interface receives a reset signal provided by the exterior interface. If the transforming interface receives a reply signal provided by the exterior interface, the first speed transmitting mode is switched to a second speed transmitting mode having a slower transmitting speed than the first speed transmitting mode. An ATAPI command is sent to the interface controller by the transforming interface through an interior BUS to dictate allowed transmitting speed to limit the writing speed of the computer storage media.
Claims4
A method for determining the transmitting mode of a computer interface to control the operating speed of computer storage device, having a servo controller, an interface controller and a transforming interface coupling to an exterior interface, the method comprising the following steps:
- using a first speed transmitting mode to output a controlling signal to the exterior interface when the transforming interface receives a reset signal provided by the exterior interface;
- switching the first speed transmitting mode to a second speed transmitting mode having a slower transmitting speed than the first speed transmitting mode when the transforming interface receives a reply signal provided by the exterior interface;
- and
- sending a ATAPI command to the interface controller by the transforming interface through an interior BUS to notify a allowed transmitting speed to limit the writing speed of the computer storage media.
