Embodiment Construction

[0012] See figure 1 , Which is a block diagram of a preferred embodiment of the hard disk of the present invention. The hard disk 10 includes a control circuit 100, a disk body 200, and an interface 300. The disk body 200 is used to store data signals. The control circuit 100 is used to control the operation of the disk body 200. The interface 300 includes multiple pins for transmitting power signals and data signals. , For the control circuit 100 and the disc body 200 to work normally, and for the control circuit 100 to exchange data signals with external devices (not shown).

[0013] The disk body 200 includes a disk disk 210, a spindle motor 220, and a magnetic head 230. The magnetic disc 210 includes a plurality of concentric tracks (not shown) for storing data signals, and the spindle motor 220 is used to drive the magnetic disc 210 to rotate. The magnetic head 230 is used to read or write data signals from the tracks of the magnetic disc 210.

[0014] The control circuit 10...

Abstract

The invention provides a hard disk including a control circuit, a disk body and an interface. The disk body includes a disk platter, a main-shaft motor and a magnetic head. The disk platter is used for storing data signals. The main-shaft motor is used for driving the disk platter to rotate and the magnetic head is used for reading the data signals from the disk platter or writing the data signals into the disk platter. The control circuit includes a main-shaft motor control circuit, a magnetic-head controller and a main-control chip. The main-shaft motor control circuit is used for controlling the main-shaft motor to drive the disk platter to rotate at a preset speed. The magnetic-head controller is used for controlling the magnetic head to be on a preset position of the disk and processing the data signals read by the magnetic head. The main control chip is used for converting and coding the processed data signals and outputting the data signals through the interface and testing the work states of the disk platter and the magnetic head and outputting corresponding state signals from the interface.

Description

Technical field [0001] The invention relates to a hard disk, in particular to a hard disk capable of outputting its own working state. Background technique [0002] Hard disk is an important component of computer equipment or server, so whether the hard disk can work normally determines the working performance of computing equipment or server. At present, understanding whether the hard disk can work normally is determined by setting a hard disk monitoring circuit on the motherboard, and determining whether the hard disk is working normally by detecting the data signal of the corresponding data input / output terminal on the hard disk slot of the hard disk backplane or the hard disk interface. [0003] However, the monitoring circuit designed on the motherboard needs to be electrically connected to the data input / output terminal of the hard disk through the hard disk slot or hard disk interface on the hard disk backplane and a series of data lines. The components themselves will be a...
