Abstract: An optical recording medium and a method for fabricating the same. A read only data region, a writable/readable data region and a content recording region are formed on a transparent substrate. The read only data region is used to store prerecording data which can only be read but is unable to be rewritten. The writable/readable data region is used to read and write data, while the content recording region is used to record initial address information of the recorded data in the read only data region, the writable/readable data region and the content recording region. A recording layer in the writable/readable data region is formed with the derivative of cyanine dye, phthalocyanine dye or azo dye. Or alternatively, the recording layer is made of an alloy containing tellurium, germanium, or antimony, or an alloy containing indium, silver, antimony or tellurium.

Abstract: An apparatus of a polishing pad conditioner and a method thereof, wherein the apparatus comprises a high-pressure water pipe for transmitting water. The high-pressure pipe is connected to an end of an ultrasonic oscillator, and another end of the ultrasonic oscillator is connected to a water tank. A spraying structure located above the water tank ejects water in the form of a water knife. The ultrasonic oscillator provides energy to the high-pressure water and the water knife is utilized to clean residue off the polishing pad. The polishing pad conditioner moves in an opposite direction from that of the polishing pad to allow the water knife of the polishing pad conditioner to clean the entire surface area of the polishing pad.
