Abstract
An optical pick-up device comprises a body, an objective lens provided on the body so as to oppose a recording medium, a laser source for producing a laser beam, a mirror for reflecting the laser beam towards the objective lens, a first table member mounted on the body of the optical pick-up device in which the first table member carries a table part such that the table part can be tilted relative to the body, an adjustment mechanism for adjusting tile of the table part of the first table member relative to the body, a second table member to which the mirror is mounted, and a connecting part of a material having elasticity and capable of absorbing vibration, interposed between the second table member and the table part of the first table member for supporting the second table member relative to the table part of the first table member.
