Now for the hard disk are head of hard disk in a circle, including head thrust head arm in turn rotary motor and head to the edge after use spacers to head out, and then use spacers or paper will head to stay back plate, in this process the central disk will be two friction, light person produce a lot of bad word, or head damaged platter scratch. (we all know that hard work is suspended between head and platters. Have damaged during loading and unloading head head experience.)

After five years of repeated grope for three years of development, a large number of experiments, overcome difficulties, (for example, concentricity, parallelism, material science, etc.) to develop the product. Key parts are using slow cutting processing technology overall accuracy of 0.01 mm parallelism is 0.02 mm. Suitable for Seagate 7200.11 and 7200.12 series of hard disk.

The basic operation method of use:
1, open the box and take out the head replacement tools, need to replace head count in the pillars on the label, and take out the corresponding copper column (in which only do basic demo)

2, the three screws on the copper column spin off and then carried out in accordance with the copper column and head of the main frame assembly, (please according to this method, three alignment, to ensure the normal use of tools, note: hex wrench to adjust the pillars at the top of the dot position tools)

3, tighten the three screws at the bottom;
