Filed: 2007-05-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical pickup device increasing with a simple constitution, a tolerance for a positional deviation of a moving path of the device itself and a radial direction of a recording disk in a direction orthogonal to the radial direction.  <P>SOLUTION: A laser beam L emitted by a light-emitting element 21 is diffracted into a main beam B20 and sub beams B21, B22 by a diffraction grating 22. A main beam B30 and sub beams B31, B32 reflected by the recording disk D are received by light-receiving elements 30, 31, 32 arranged side by side in a direction corresponding to the radial direction of the recording disk D. Normally, a tracking error signal is obtained by a three-beam method on the basis of the outputs of the light-receiving elements 31, 32. Because the main beam B20 and the sub beams B21, B22 are positioned in the radial direction, even when the position of an objective lens 26 is deviated in a direction orthogonal to the radial direction due to an inferior assembling accuracy, the positional relationship between the positions irradiated with the main beam B20 and the sub beams B21, B22 and a track of the recording disk D is not drastically deteriorated.  <P>COPYRIGHT: (C)2009,JPO&INPIT
