Abstract

An adaptive eg video disc record stylus kicker (46) system for inducing limited pickup or stylus (14) translations radially across the disc record (12). Control circuitry (54) responsive to disc track and disc angular sector identification signals automatically calibrates the kicker activation signals (51) to produce a desired kicker induced stylus translation. That is, the control circuitry responsive to these track identification signals and to player commands (53) evaluates the error between actual kicker induced stylus translations and the programmed kicker induced stylus translations. A microprocessor (56) establishes a table containing kicker control signals for driving the kicker in each sector of the disc. For a given kicker induced stylus translation, the error is calculated between the actual stylus translation and the programmed stylus translation and the control signal for the respective sector is adjusted accordingly. Subsequently, the control signals for each of the other sectors are altered proportional to the adjustment made to the particular control signal in accordance with a correlation function. The system operates to correct mistracking (identification signals do not appear in the correct sequence) due, e.g. to record defects.
