Abstract
For higher density optical disks, it has been examined whether the partial response maximum likelihood (PRML) method can be used for signal detection. There have been, however, few theoretical studies about this method under the condition that the readout signal is deteriorated by various kinds of factors. We have developed a PRML simulator for optical disks to evaluate the PRML method theoretically taking, for example, crosstalk and disk tilt into account. We report the configuration of this PRML simulator and some results the simulator has yielded.
