  • Page 33 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 HD153722 using DPP(Differential Push-Pull) Method(CD) and PP(Push-Pull) Method(DVD). DPP Method uses not only main beam(EF1~EF4) but also side beam(E, F) for correcting DC offset generated in Push-Pull Method.

Self-Diagnostic Function by LED Blink. • Basic operation: MPU is included in DSP, MPU accesses each peripheral (inside, exterior) device, and discover a defect by the ability of a read/write of data to be performed correctly. Since MPU operates by the program with a built-in Flash-ROM, when abnormalities are in MPU, Flash-ROM, and these Data-Bus &...
