Abstract
According to the invention, an optical disc reproducing apparatus includes a housing for: a reading section which reads data recorded on an optical disc, a data storing section and a reproducing section which reproduces the stored data. A reference discal unit outside the housing rotates at a pre-determined reference rotational speed and direction. An operation discal unit mounted on the reference discal unit, may rotate at a desired speed and direction. A detection discal unit is coupled with the operation discal unit, to rotate in sync with the operation discal unit. First and second detecting sections detect a rotational speed and direction of the detection discal unit and the reference discal unit, respectively. A control section determines the rotational speed and direction of the detection discal unit based on detected results and controls the reading section, the storing section and the reproducing section, thereby performing a desired data reproduction.
