Description

  The present invention relates to a glass hard disk cleaning apparatus capable of efficiently cleaning a hard disk made of glass material.

  The hard disk has a large memory capacity, has a clear image, is suitably used as a memory for music and moving images, and has been developed for various uses such as a mobile phone, a video camera, and a personal computer. This hard disk is made of an aluminum material or a glass material. As a disk size, for example, 0.85 inch has an outer diameter 22 mm × inner diameter 6 mm, 1.0 inch has an outer diameter 27.4 mm × inner diameter 7 mm, and 1.8 inch The outer diameter of 48 mm × the inner diameter of 12 mm and the 2.5 inch are made in a disk shape having a central hole such that the outer diameter is 65 mm × the inner diameter is 20 mm, and those having a large diameter are used according to the memory capacity.

In order to manufacture the hard disk made of the glass material, the disk glass is cut to a disk size, and the inner and outer diameters are polished by a grinder and finished. This finish is polished by double-sided polishing (see, for example, Patent Document 1), but in order to efficiently manufacture at a high cleaning level, the entire surface is physically cleaned by about 1000 to 1500 sheets per hour without drying the disk. In other words, it is difficult to perform cleaning with such high efficiency in the conventional methods. It is possible to improve the efficiency by cleaning the hard disk while transferring it horizontally as in the case of wafer cleaning. However, as described above, there are various sizes of hard disks. It is troublesome to make it. Further, since a hard disk made of glass material becomes transparent when wet with water, it is difficult to easily detect it from above with a sensor, and thus it is difficult to obtain a control signal for controlling the cleaning line.
