Embodiment Construction

[0020] Below in conjunction with accompanying drawing and preferred embodiment the present invention is described in further detail:

[0021] Please refer to figure 1 , a preferred embodiment of the host 110 of the present invention includes a motherboard 10 and a hard disk 102 . The motherboard 10 includes a power supply circuit 100 , a buffer circuit 101 and a control circuit 103 . In this embodiment, the power supply circuit 100 is used to provide various types of power, such as a 5V power, a 12V power and a 3V power. The power supply circuit 100 is used for providing the hard disk 102 with working voltage. In this embodiment, the hard disk 102 is used for data storage and read / write operations. The hard disk 102 includes a magnetic head 107 and a magnetic disk 105 . Wherein, the magnetic head 107 can be suspended on the magnetic disk 105 when the magnetic disk 105 rotates.

[0022] The control circuit 103 is used to receive the power output from the power supply circu...

Abstract

The invention discloses a mainboard. The mainboard comprises a power supply circuit, a control circuit and a buffer circuit. The control circuit is used for receiving a plurality of power supplies output by the power supply circuit; and the control circuit is further used for receiving an instruction output by a chip and controlling the movement of a disk head according to the instruction. The buffer circuit performs energy storage operation when receiving the power supplies; when not receiving the power supplies, the buffer circuit performs discharge operation within a preset time and outputs a corresponding control voltage to the control circuit; and when receiving the control voltage output by the buffer circuit, the control circuit moves the disk head to a zero track of a disk within the preset time. The invention furthermore provides a host. The mainboard and the host with the same can move the disk head to the zero track through a delay effect during sudden power failure, thereby avoiding hard disk damage caused by sudden power failure.

Description

technical field [0001] The invention relates to a main board and a host with the main board. Background technique [0002] During the normal working process of the computer, the platters of the hard disk rotate at a high speed, generally 5400-7200 rpm. When the power is normally turned off, the head of the hard disk will return to the zero track. However, when the power supply is suddenly cut off, because the magnetic head of the hard disk is suspended when reading the disk normally, at this time, the magnetic head may fall due to the sudden power failure, which may cause damage to the hard disk, such as hard disk signal errors, Damage such as bad sectors occurs. Contents of the invention [0003] In view of the above, it is necessary to provide a main board which can avoid hard disk damage due to sudden power failure and a host with the main board. [0004] A motherboard, comprising: [0005] A power supply circuit for outputting a plurality of power supplies; [000...
