Abstract
A tracking error signal generating apparatus for use in a recording and reproducing system employing a disk on which is formed an information track comprising a pair of tracking markers and a time-division servo signal including a sync signal. An error is calculated from any two of the tracking marker data obtained from the disc and a series of error data is generated. Furthermore, a series of corrected error data is generated by respectively inserting at least one neighboring value of adjacent two data between the adjacent two data of the error data, and each of the corrected error data are converted to form an analog signal.
