The ink B is blue ink or bluish white ink and absorbs the illumination light in the yellow wavelength range on the wedgelike tip side, and the extent of this absorption decreases gradually toward the incidence surface side.

Filed: 1985-10-07
Abstract: PURPOSE:To obtain the titled control mechanism that ensures the high accuracy and high workability with no addition of exclusive parts, by turning a pickup vertically centering on a guide shaft to control the light illuminating angle to a disk. CONSTITUTION:In case the laser light is not made incident vertically on the surface of a disk unlike an optical axis (l), a shaft 7 is turned by fastening and unfastening a screw part 8. As a result, a flange part 9 moves forward or backward in response to the forward or backward movement of the part 8. The a roller 6 moves on a slide surface in the direction crossing the sliding direction. Thus a pickup 3 turns slightly round a shaft 10 toward an arrow head Y and therefore the optical axis of the laser light can be tilted toward l' or l''. In such a way, the light illuminating angle of the pickup 3 can be controlled so that the laser light is made incident vertically on the disk surface by turning the shaft 7 to give the forward or backward movement to the pickup 3.
