An optical disc system and a method of managing shock while recording or
playing data in the optical disc system are provided. The optical disc
system includes an optical pick-up unit for applying a laser beam to a
track of an optical disc and detecting reflected light, a servo unit for
controlling tracking and focus of the optical pick-up unit and a
monitoring unit for comparing a monitoring signal, which is output from
the optical pick-up unit and the servo unit, with a reference signal and
generating a blocking signal and a blocking release signal. Recording or
playing of data on the optical disc is stopped in response to the
blocking signal, and recording or playing of the data on the optical disc
is resumed in response to the blocking release signal based on a state of
the optical disc system when recording or playing was stopped.
