Problems solved by technology

Its disadvantages are: when the micro hard drive is performing self-servo writing, the high-speed rotation of the motor spindle will cause the vibration of the disc. When many micro hard drives are working, the vibration caused by the high speed is transmitted to the rack, which may cause resonance; The received external vibration or impact will also be transmitted to the hard disk
The impact between the hard disk and the rack, and the resonance between the metals will interfere with the writing work, resulting in a reduction in the quality or failure of the servo writing, and a reduction in the yield. At the same time, long-term vibration will also affect the life of the micro hard disk.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] figure 1 As an embodiment of the present invention, the shock-isolation table 1 is a marble table. The marble table is rectangular in shape and has a considerable thickness to form a stable work surface. At the same time, it buffers and offsets external forces and isolates external vibrations. There are four brackets 2 with the same structure on the marble countertop. The number of brackets 2 can be appropriately increased according to the needs of servo writing. The brackets 2 can be made of steel and have a firm structure. Five hard disk shock absorbers 5 are placed on them. Compact and space-saving, bracket 2 protects the hard disk like a helmet, giving the hard disk a good working environment.

[0018] For further isolation of external vibrations, a rubber block 4 can be set between the support 2 and the marble table top, and its top is connected with the s...

Abstract

The present invention belongs to the field of photo electronic device, and is especially one damping frame for servo recording micro hard disc. The frame of the present invention is one metal frame connected to a shock isolating stage and possessing inside notch for hard disc damper to be inserted in. The hard disc damper consists of U-shaped metal plate and rubber pads fixed to the sides and the bottom of the metal plate, with the side rubber pads being screwed to the frame and the bottom rubber pad being screwed to the hard disc board. The frame may be used for simultaneous recording of several micro hard discs in high recording quality.

Description

technical field [0001] The invention belongs to a frame for loading optoelectronic products or devices, in particular to a shock-absorbing frame which is self-servo-written by multiple microhard disks at the same time, and is easy to absorb and absorb shocks and improves the quality of writing. Background technique [0002] With the mass use of various electronic products such as MP3 / MP4 players, digital cameras, digital video cameras, PDAs, and mobile phones, the wide application of micro-hard disks will surely become a trend of future development. At the same time, the micro-hard disk industry is also facing ultra-high track density. The challenge of magnetic storage technology also puts forward very high requirements for the positioning accuracy and accuracy of servo writing of micro hard drives. [0003] Servo writing is an important link in the production process of micro hard drives. The traditional servo writing method requires two external devices to write servo info...
