Abstract
A transfer control system of an information read beam for transferring an information read beam from one recording side to another in an information reader comprising offset error signal generation means for piggybacking a predetermined offset level onto a focus error signal indicating a shift from the focus position of the information read beam to generate an offset error signal in order to shape the beam form of the information read beam for reading record information from an information recording medium having a plurality of laminated recording sides on the recording side. It comprises offset level setting means for setting the predetermined offset level in the offset error signal generation means, transfer signal generation means for generating a transfer signal for forcibly transferring the information read beam, and transfer means for transferring the information read beam from one recording side to another based on the transfer signal. The transfer signal generation means generates the transfer signal after the offset level setting means clears setting of the offset level.
