Abstract: When an optical disc apparatus reproduces information from an optical disc, it converges a reading light beam emitted from an LED to substantially collimated light and projects it to the optical disc to cause it to be reflected by reflection surface thereof so as to make it become a reading reflected light beam. Then, the apparatus converges the reading reflected light beam by a mark layer selection lens, detects the reading reflected light beam passing through the target position by a detection region located at the confocal point of the target position and generates a detection signal. Subsequently, the apparatus recognizes the presence or absence of a recording mark based on the detection signal to reproduce the information. Thus, the apparatus can detect the state of the reading reflected light beam observed when it passes the target position and can recognize the presence or absence of a recording mark.

The first container (4) has a wall-shaped inner side wall that corresponds to the shape of a cylinder bore wall (7). Provided on this inner side wall is a flexible structural part (8). The flexible structural part (8) is formed of highly elastic resin. The second container (5) has a similar structure.
