Disk reproducing apparatus

A disk reproducing apparatus comprising:

• a disk driving unit for rotating a disk;
• an optical pickup assembly having a movable base member and a pickup main body supported on the movable base member;
• a guide shaft mounted on a stationary base for guiding said movable base member supporting said pickup main body;
• guide bearings formed on an edge portion of said movable base member through which said guide shaft is slidably inserted;
• a single guide face only discretely formed on a lower surface of another edge portion of the movable base member so as to extend in the direction along which said guide bearings are separated from each other;
• said stationary base having a guide member directly and fixedly formed on only one discrete portion thereof with a generally circular cross-section on which said guide face slidably contacts, said guide member facing said guide shaft with said pickup main body being positioned between said guide member and said guide shaft, said guide member having a length shorter than a sliding distance of said pickup main body in a guiding direction, wherein said guide member is arranged to only contact said single guide face in substantially only a line contact to thereby obtain an increased feeding accuracy of the pickup main body, and wherein the feeding accuracy of the pickup main body is substantially determined only by accuracies of the movable base member and the guide member;
• a pickup driving unit for driving a pickup of said pickup main body in the radial direction of said disk;
• and
• a signal processing unit for applying a specified processing to a signal reproduced from said pickup.
