Abstract:
An information reproduction apparatus comprising:an information read out means unit (230, 500) responsive to a supplied control signal for reading and disposed to read out information from a mounted recording medium, a reproduction means circuit (90) for demodulating disposed to demodulate said information to generate reproduction data, a first period signal detection means circuit (130) for detecting disposed to detect a first period signal from read out said information, a synchronizing signal generation means circuit (170) for generating disposed to generate a plurality of synchronizing signals of different phases according to detected said first period signal, a second period signal detection means circuit (190) for detecting disposed to detect a second period signal from read out said information, and a control means circuit (210) for disposed to selectively supplying supply as said control signal to said information read out means circuit a synchronizing signal out of said plurality of synchronizing signals generated by said synchronizing signal generation means circuit that has a predetermined phase difference from said second period signal detected by said second period signal detection means circuit.
