Problems solved by technology

The microprocessor executes a program to maintain communication with the hard disk drive, and sequentially commands the hard disk head to retract, but this continuous operation takes a relatively long time. May have hit the disk surface
In addition, the design is complex, the system overhead is high, and it relies on the operation of the microprocessor and the timely response of the hard drive to prevent the disk from being damaged

Embodiment Construction

[0013] Please refer to figure 1 , the portable computer 10 of the present invention includes a central processing unit 11 and a hard disk drive unit 12 . This hard disk drive unit 12 comprises a hard disk device 13, and this hard disk device 13 comprises a magnetic disk, a magnetic head, an exciter and an axle center, and above-mentioned elements are all packaged in a casing, and this hard disk drive unit 12 also comprises a control hard disk drive When the computer 10 is working normally, the microprocessor 14 communicates with the central processing unit 11, and transmits and receives signals between the magnetic head and the magnetic disk of the hard disk device 13.

[0014] An acceleration sensor device 16 is connected to the control microprocessor 14, and the acceleration sensor 16 is used to detect the acceleration of the computer when it is moving, and transmit a signal to the microprocessor 14.

[0015] Please refer to figure 2 , figure 2 A working flow diagram of...

Abstract

In the present invention, the accelerated speed sensing device is used to detect whether computer is at moving state of free-failling body. A signal is transmitted to microprocessor at the time that this state is detected and the microprocessor orders magnetic head movable device to draw back magnetic head from magnetic disc surface after it detects the state for the time as long as a pre-set time so that the hard disc damage caused by the magnetic head impact can be avoided.

Description

【Technical field】 [0001] The invention relates to a protection device and method for a hard disk drive of a portable computer, in particular to a protection scheme for stopping the magnetic head of the hard disk drive when the portable computer falls. 【Background technique】 [0002] Today's portable computers of all types have a tiny hard drive that can be subjected to shocks that can severely damage the hard drive in some cases. [0003] Since the distance between the magnetic head of the drive and the disk platter is very small under normal working conditions, when the computer is shaken, the magnetic head is easy to touch the magnetic disk, thus causing damage to the magnetic head, and in severe cases, it will scratch the magnetic disk and destroy the recording on the magnetic medium. data, a phenomenon known as "head crashing" that can cause irreparable data corruption. [0004] Therefore, how to effectively prevent the contact between the magnetic head and the magnetic...
