description	The specification discloses a method and apparatus for providing speed control and rotational indexing of a disc recorder, based upon a particular use of a plurality of electrical pulses produced, for example, as the slots of a slotted wheel, axially coupled to a recording disc, pass a transducer. The primary repetition rate of pulses in response to equally-spaced slots is used for speed control of the recording disc. A secondary pulse rate occurring between two successive pulses resulting from adjacent slots with different spacing is used to establish an index pulse correlated with a reference point on the disc.
