A disc drive is constructed from a main body which includes a mechanism unit having a disc rotating mechanism for rotating a disc and a play back mechanism for playing back information recorded on the disc, disc tray movably provided with respect to the main body for supporting a disc and a casing for housing the main body. The disc drive is provided with vibration absorbing members for suppressing transmission of vibration caused by high speed rotation of the disc from the main body to the casing. The vibration absorbing members are formed of elastical members and they are arranged between the side portions of the main body and the inside of the casing, thereby the main body is supported by the casing through the vibration absorbing members to prevent vibrations caused in the main body from being transmitted to the casing. Further, the casing has a U-shaped side plate and a top plate fixed to the side plate by screws, in which the top plate is in point contact with the side plate through a plurality of protrusions formed on upper edges of the side plate. This point contact between the top plate and the side plate makes it possible to prevent rattling from being caused by the transmitted vibrations, thereby preventing generation of noise.
