Abstract

The invention discloses an energy-saving device and a method for operating the power-saving device. The energy-saving device comprises a controller, a servo motor, a power recovery unit and a reading head. The controller judges the running mode of the energy saving device. The servo motor receives a first control signal from the controller and operates according to the first control signal. The power recovery unit recoveries the redundant energy of the servo motor and converts the redundant energy into recovery power. The reading head is floated on the surface of a disc or is placed in a parking zone according to a second control signal of the controller. The controller enables the power recovery unit to recovery the redundant energy of the servo motor when the controller controls the energy-saving device not to perform the maximum energy consumption action.

Description

technical field [0001] The present invention relates to an energy-saving device and an operating method of the energy-saving device, in particular to a hard disk capable of recovering excess energy. Background technique [0002] In the trend of environmental protection, the efficiency of computer products often runs counter to energy saving. At present, in order to achieve the purpose of energy saving on the hard disk device, it is mainly to improve the energy consumption of the electronic circuit, and to reduce the power consumption time by increasing the transmission speed. However, once the transmission speed is increased, the accompanying power consumption will also increase. For example, the read and write performance and power consumption of a hard disk are intertwined, so the room for improvement in performance and power saving of a single hard disk is very limited. . At present, most hard disk drives focus on energy saving when the system is lightly loaded. But for...
