摘要：PURPOSE: A modeling apparatus of high density optical disk channel is provided to generate playback signal in real time and to shorten development period by having a disk channel emulator and supplying any data column to the disk channel emulator. CONSTITUTION: A data source generating part generates source data modulating any data column. A disk channel modeling part makes a linear modeling source data and compensates non-linearity and generates sample data. A controller(14) controls the disk channel modeling part. A high density disk channel modeling apparatus is composed of a source sequence generator(2) which generates source sequence, a disk channel emulator(8) which generates sample data making a linear and non-linear modeling source sequence from the source sequence generator(2), the controller(14) to control the disk channel emulator(8) and D/A(digital to analog) converter(16) converts sampling data from the disk channel emulator(8) into analog signal.
