Abstract

A signal quality measurement method for high density optical read/write system was presented. A partial response maximum likelihood (PRML) was used as the data detector and the 31-tap finite-impulse response (FIR) filter as channel characteristics detection filter. The signal quality detector changes the signal quality into numerical value and has higher similarity to the bit error rate performance curve of the detector. The results show that the proposed detector is the proper index forsignal quality as it is able to detect the tangential and radial tilt area.
