Method and apparatus for recording digital signals medium for recording digital signals and method |
摘要 |
An excellent waveform signal with less jitter is obtained as an output signal from a reproducing optical pickup, irrespective of a relative reading speed. Thus there is no need for an equalizing circuit on a reproducing apparatus side. An input bit sequence or a recording NRZI signal is combined with spatial frequency characteristics G(fs) by a G(fs) converter. An output signal from the G(fs) converter is combined with equalizing frequency characteristics EQ(fs) necessary on a reproducing side by an EQ(fs) converter. An output from the EQ(fs) converter is saturation-amplified by a saturation amplifier, thereby producing an ideally pre-jittered recording signal that has equivalent enhanced high-frequency component. The recording signal is recorded on an optical disk.
