Popis:	The Partial-Response Maximum-Likelihood (PRML) signal detection method is well known as an effective way to improve the recording density of a magneto-optical (MO) disk system. We have developed a PRML simulator to evaluate various PRML systems for MO recording. This report presents the performance evaluations of various PRML systems based on computer simulations to find bit error rate (BER) characteristics. Calculation of BER was made under the condition that the wave front aberration caused by tilt of the disk and defocus of the optical head is given to the readout beam.
