A recording apparatus for optical data includes a photo detection IC for producing a plurality of phase signals; a plurality of sample/hold (S/H) circuits electrically connected to the photo detection IC; a plurality of limiter circuits electrically connected to the photo detection IC; a channel signal generator connected to the S/H circuits; and a level shift circuit connected to an output of the channel signal generator. The recording apparatus for optical data prevents the interference of servo signal during high speed operation and ensures normal operation of S/H circuits thereof.
