Abstract:
We present a method to calculate the readout signals from
optical disks and their applications. Our method is based on a convolution operation of marks recorded on a disk and an extended
point spread function (EPSF). Our method can be applied to the case where the marks are recorded in a groove and the photodetector has
an arbitrary shape. Four analyses examples are reported: analysis of the tracking error detection method termed the differential phase
detection (DPD), focus shift dependency of readout signal jitter when the marks are recorded in a groove, EPSF for land and groove
readout, and a compatible readout method for digital versatile disks and compact disks.
