Optical pickup head of optical recording reproducing apparatus, fabrication method thereof, lubricant-coated optical pickup head of optical recording reproducing apparatus and lubricant coating method thereof

A method for fabricating an optical pickup head of an optical recording reproducing apparatus, comprising steps of:

• preparing a mother material on which an insulating layer is arranged and a silicon layer is laminated on both sides of the insulating layer;
• forming a lower body having a lower fixed electrode at a side of the mother body by using a certain semiconductor device fabricating processes, forming an upper body having an upper fixed electrode at the other side and forming a moving body installed between the upper and lower fixed electrodes so as to be movable and have a moving electrode alternately arranged between the upper and lower fixed electrodes;
• joining the material obtained by the preparing step to a slider;
• and
• combining a convergence lens with the body.

A method for coating lubricant on an optical pickup head, comprising steps of:

• forming a silicon dioxide film onto upper and lower fixed electrodes, a moving electrode and an air bearing surface of a slider by dipping an optical pickup head into hydrogen peroxide;
• eliminating the rest hydrogen peroxide on the upper and lower fixed electrodes, the moving electrode and the air bearing surface of the slider by dipping the optical pickup head in a toluene solvent;
• coating lubricant on the upper and lower fixed electrodes, the moving electrode and the air bearing surface of the slider by dipping the optical pickup head in the lubricant;
• and
• eliminating the rest lubricant on the upper and lower fixed electrodes, the moving electrode and the air bearing surface of the slider by dipping the optical pickup head in a solvent.

A method for coating lubricant on an optical pickup head, comprising steps of:

• forming a hydrogen peroxide film onto upper and lower fixed electrodes, a moving electrode and an air bearing surface of a slider by installing an optical pickup head in a flow channel in which hydrogen peroxide flows;
• eliminating the rest hydrogen peroxide on the upper and lower fixed electrodes, the moving electrode and the air bearing surface of the slider by making a toluene solvent flow in the flow channel;
• coating lubricant on the upper and lower fixed electrodes, the moving electrode and the air bearing surface of the slider by making the lubricant flow in the flow channel;
• and
• eliminating the rest lubricant on the upper and lower fixed electrodes, the moving electrode and the air bearing surface of the slider by making a toluene solvent flow in the flow channel.
