<p>A disk reproducing system comprising a pickup (1) for reading information from an information disk (2) on which data is recorded at a constant linear velocity, a disk motor (16) for turning the information disk (2), a digital signal processing means (7) for digitizing data according to the reproduction format of the disk (2), an interfacing means (19) for sending the digitized data to an external device, and a buffer memory (18) for storing temporarily the data, the system further comprising a means for detecting the linear velocity and traffic pitch of the disk (2) to determine a speed control reference value of the disk motor (16) from the detected linear velocity and traffic pitch and from a maximum diameter of a data recording region, whereby a highest reproduction velocity of the system can be obtained even on disks with different traffic pitches.</p> |
