Abstract

There have been various kinds of methods to measure the signal quality of optical discs. Until now the jitter method has been the most popular way for measuring the signal quality, but unfortunately in the high density recording system it is not able to express the signal quality accurately due to the increase of ISI. In this paper a new method is proposed to measure the signal quality for the high-density recording systems. It is based on the idea of an eye pattern, which has a strong relation to the symbol error rate of the PRML system. It can even express the performance of the PRML system in detail range where the jitter method can't present the information of the PRML system.
