Reproducing apparatus having a single microprocessor to perform data

Abstract

A disc reproducing apparatus for an optical disc on which data is recorded. The reproducing apparatus reproduces data recorded on the disc as reproduced data, and, in response to a user input, performs data retrieval, a process in which the data to be reproduced from the disc is selected. The apparatus comprises a main body section and a display, attached to the main body section, for displaying reproduced data. The main body section includes an optical pickup that provides signals in response to the disc, a signal processing circuit that processes the signals from the optical pickup means to provide reproduced data, a feed motor that moves the optical pickup radially relative to the optical disc, and a feed motor control that controls the feed motor. The main body section also includes a device that rotationally drives the optical disc, and an input device that receives the user input. Finally, the main body section includes a control device that includes a single central processing unit. The control device performs a data retrieval operation in response to the input device, and generates a timed interrupt, in response to which, the control device suspends the data retrieval operation, and performs a disc reproduction control operation, including controlling the feed motor control. Upon completion of the disc reproduction control operation, the control device resumes the data retrieval operation.
