HARD DISK DRIVER HAVING LOW-POWER OPERATION MODE AND METHOD FOR CONTROLLING OPERATION SPEED OF THE SAME

摘要

In the present invention, it is activated with a low-power operating condition for a hard disk drive and operability adjusting method. A hard disk drive according to the present invention is characterized by having interface section, velocity response unit, a controller and speed control. It is responsible for signal between host and hard disk drive interface unit to send. Detection data transmission mode corresponds to rate of data signalling to export the low-speed detection signal in the case where data mode is switched in a manner of lower rate transmissions in normal transmission mode between host and interface rate induction unit. It says the controller for receiving low-speed detection signal and exports a control signal, is used to control the service speed of service speed and hard disk drive. Speed control unit operation speed control signal is received to convert the mode of operation of the speed of hard disk drive, there is the low-power operating condition in the regular mode of operation. ;Hard disk and power consumption, transmission speed, operating rate
