Track cross signal correction apparatus |
摘要 |
A track cross signal correction apparatus removes noise components contained in a track cross signal. The apparatus includes mask signal generator for comparing pulse widths of the received track cross signals with threshold values, based on the pulse width of a previous track cross signal. A mask signal is generated according to the comparison result. A corrector outputs a received track cross signal when mask signals are generated from the mask signal generator. The track cross signal correction apparatus accurately performs a track seek operation in a medium such as a CD-ROM which requires high-speed access.
