Abstract: There is provided an optical disc drive that can guide the center of an optical disc to the position of a spindle motor, while allowing the number of components to be reduced. A base frame includes a stopper portion that comes into contact with an outer edge of the optical disc having reached the position of a spindle motor and that restricts backward movement of the optical disc. A switch arm includes a contact portion located on a side opposite to the stopper portion across the optical disc having reached the position of the spindle motor, and the switch arm uses the contact portion to push the optical disc toward the stopper portion.

Abstract: A sheet body 30 includes first and second sheets 40 and 60 that transmit infrared radiation. A rear face of the first sheet 40 is opposed to a front face of the second sheet 60. An information code is marked on a front or rear face of the second sheet 60 by using an infrared absorbing material. The rear face of the first sheet 40 and the front face of the second sheet 60 are stuck together with a highly infrared transmitting adhesive. The front face of the first sheet 40 is marked with a pattern using an infrared transmitting material that is visible when visible radiation is irradiated onto the pattern.

Abstract translation: 片体30包括透射红外线的第一和第二片40和60。 第一片材40的后表面与第二片材60的前表面相对。通过使用红外线吸收材料，在第二片材60的前表面或后表面上标记信息代码。 第一片40的后表面和第二片60的前表面与高红外透射粘合剂粘合在一起。 第一片40的前表​​面使用在可见光辐射到图案上时可见的红外透射材料标记图案。
