ABSTRACT:
A disc device comprising a transfer unit operable to provide a transferring force to a disc inserted from the outside to transfer the disc into a storage area in the device, a sensor unit for detecting the position of the inserted disc, and a control unit for controlling a operational speed of the transfer unit. The control unit controls the operational speed of the transfer unit in the disc loading direction at a low-speed until the disc inserted from the outside reaches the transfer unit. The control unit then adjusts the operational speed of the transfer unit in the disc loading direction from a low-speed to a high-speed when the sensor unit detects that the disc is inserted into the position in which a transferring force from the transfer unit is given to the disc, or after a predetermined period of time has elapsed. Accordingly, the disc device reduces operation noise and resistance when the disc is inserted.
