OPTICAL PICKUP DEVICE

PURPOSE:To keep a sliding state between the bearing part, and the guide shaft of a holder blade at a good condition, and to improve the reliability of the operation of an optical pickup, by forming a uniform solid-state lubricant thin film on either plane the inner peripheral plane of the bearing part, or the outer peripheral plane of the guide shaft of the holder blade, in a range of thickness of 1-3mum. CONSTITUTION:The bearing part of the holder blade 1 having a lens holding part 1a, and the bearing part, is fitted in the guide shaft 5 provided protrusively at a pickup main body 4 in such a way that it can be moved slidably, and the holder blade is moved reciprocally in the axial direction of the guide shaft by a magnetic circuit 6. In this case, the solid-state lubricant thin film having the thickness in the range of 1-3mum, and also formed uniformly, is formed on either plane the inner peripheral plane of the bearing part, or the outer peripheral plane of the guide shaft of the holder blade. In this way, it is possible to generate a good sliding state between the bearing part, and the guide shaft of the holder blade, and to prevent the malfunction of the optical pickup from generating.
