Abstract
A device for repairing the surface of optical disk is composed of base, rotary seat, top cover, grinding drum and drive mechanism. The rotary seat with the disc receiving surface is rotatably arranged on the base so as to receive the optical disc. One side of the upper cover is pivoted to the edge of the base and can cover the base. The grinding roller with the grinding layer on the surface is rotatably arranged on the inner surface of the upper cover, and the grinding roller traverses the disc bearing surface of the rotating seat. The driving mechanism is arranged between the rotary seat and the grinding roller, so that one surface of the grinding roller rotates to grind the laser transmitting layer surface of the optical disk, and simultaneously drives the rotary seat to rotate, so that the optical disk placed on the disk receiving surface of the rotary seat rotates simultaneously. The utility model discloses can exert more even grinding pressure to the readable face of CD, make the grinding effect more even, more can not harm the readable face of CD, and have less volume, make it carry or collect more easily.
Description
Technical field
The utility model relates to the lapping device on a kind of laser disc surface, relate in particular to and a kind ofly can apply average grinding pressure the readable face of laser disc, make grinding effect more even, more can not damage readable of laser disc, and have smaller volume, make it the easier laser disc surface repair apparatus that carries or collect.
Background technology
Since laser disc (Compact Disc is called for short CD) comes out, traditional disc and audiotape have just been replaced fast.Then at short notice, compact video disc (Video Compact Disc is called for short VCD) is come out one after another, and has replaced traditional video tape.Also invented the compact disk read only memory (Compact Disc Random Only Memory is called for short CD-ROM) that is applied to record computer information in recent years, and the laser disc that can repeat to write (Compact Disc Re-Write is called for short CD-RW).Add digitized video laser disc (Digital Video Compact Disc is called for short DVD).These video discs all are to smear one deck laser photic zone from the teeth outwards, when clean wiping laser photic zone, are difficult to avoid by scratch.In addition, in use or in the collection process, careless slightly also scratch laser photic zone very easily, and when laser radiation to by the laser photic zone of scratch, laser can produce abnormal refraction, correctly reading signal.If abandon at this point by the laser disc of scratch, for the user, not only cause damage, even may be disc, film out of print by the laser disc of scratch, or very important data.So if can rescue the laser disc of these damages,, or avoid causing to remedy sorry with person's capable of reducing using loss.
In order to solve this problem, existing technology is to utilize limber abrasive wheel, with perpendicular to readable of laser disc, and the readable face of laser disc is pressed, and makes the abrasive wheel distortion, makes it smooth in readable of laser disc, and spin finishing again is to readable grinding of laser disc.But there is following shortcoming in this structure:
1. readable zones of different that contacts with abrasive wheel of laser disc, suffered grinding pressure is widely different, because the bigger zone of abrasive wheel deflection must apply bigger pressure to the readable face of laser disc; And the less zone of abrasive wheel deflection must apply less pressure to the readable face of laser disc.Cause grinding pressure extremely unequal, not only grinding effect is not good, and excessive grinding pressure can damage readable of laser disc on the contrary.
2. the shared volume of a whole lapping device is too big.Because abrasive wheel must be across readable of the laser disc of ring-type, so its diameter must be greater than the ring-type width of readable of ring-type laser disc, adding abrasive wheel must cause whole the shared volume of lapping device too big perpendicular to readable of laser disc, is unfavorable for carrying or collecting.
