<P>PROBLEM TO BE SOLVED: To provide an optical pickup which has high performance, is inexpensive and cause no reading error. <P>SOLUTION: In this optical pickup for reading information recorded on a disk by projecting a laser beams from a semiconductor laser LD to the disk through a half-mirror, a collimator lens and an object lens and receiving its reflected light with a photodiode PD through the half-mirror, a notch part 6b is formed by notching a metal plate of a pattern corresponding to a connector pin 91 part where a high frequency signal of a printed board 6 is caused to flow from a metallic board main body 6a, electrostatic capacity is prevented from occurring between the metallic board main body 6a and the printed board 6, and jitter is prevented from occurring in a reading signal of the photodiode PD. <P>COPYRIGHT: (C)2003,JPO |
