<p>A disc drive in which sufficient rigidity can be attained even when a material of low rigidity, e.g. an aluminum alloy or a magnesium alloy, is employed and malfunction due to deformation of the chassis enclosure can be prevented. The chassis enclosure is constituted of a base body (10) and a lid body, a disc insertion opening (11) for inserting a disc directly is formed in the front surface of the chassis enclosure, a deep bottom part (210) and a shallow bottom part (310) are formed in the base body (10), the shallow bottom part (310) is arranged on the side part of the deep bottom part (210), and the deep bottom part (210) and shallow bottom part (310) are covered with the lid body. The disc drive is characterized in that a first squeezing groove (136A) of a predetermined length projecting toward the base body (10) side, and a second squeezing groove (136B) of a predetermined length projecting toward the side opposite to the first squeezing groove (136A) are formed at the front surface side end part of the lid body.</p> |
