  • Page 30 3-2-1. Tracking Servo The aim of tracking servo is to make laser beam trace the data track on disc. Tracking Error(TE) Signal is generated from tracking error detected block in MT1959H using DPP(Differential Push-Pull) Method and DPD (Differential Phase Detection) Method. DPP Method uses not only main beam(A, B, C, D) but also side beam(EF1~EF4) for correcting DC offset generated in Push-Pull Method.
