Abstract: The present invention relates to an antigen-binding molecule comprising a heavy chain variable region comprising a heavy-chain complementarity-determining region 1 (HCDR1) comprising an amino acid sequence represented by Sequence No. 1, an HCDR2 comprising an amino acid sequence represented by Sequence No. 2, and an HCDR3 comprising an amino acid sequence represented by Sequence No. 3; a light-chain variable region comprising a light-chain complementarity-determining region 1 (LCDR1) comprising an amino acid sequence represented by Sequence No. 4, an LCDR2 comprising an amino acid sequence represented by Sequence No. 5, and an LCDR3 comprising an amino acid sequence represented by Sequence No. 6; wherein the antigen-binding molecule is a T cell receptor (TCR); and to a cell line expressing the same.

Abstract: A tracking method discriminates whether an optical disc loaded in a recording and/or reproduction system is a shallow groove type optical disc or a deep groove type optical disc, and corrects the phase of the tracking error signal detected from the optical disc according to the discrimination result, to then perform a tracking servo control using the corrected result. A tracking apparatus includes an optical signal detector detecting a tracking error signal from an optical disc loaded in a recording and/or reproduction system. A groove type discriminator analyzes the tracking error signal output from the optical signal detector to discriminate a groove type of the loaded optical disc and generates a corresponding control signal. A phase corrector corrects the phase of the tracking error signal output from the optical signal detector according to the control signal applied from the groove type discriminator.
