Recording apparatus for generating write pulse control signals suitable for various types of optical recording media
Abstract:
A recording apparatus for generating write pulse control signals suitable for various optical recording media includes a pattern detector receiving a non return to zero inverted (NRZI) signal and distinguishing between information about a mark and information about a space, a memory storing timing parameters for a start pulse, a middle pulse, an ending pulse, and a cooling pulse of the write pulses corresponding to each of the various recording media using an activation table or in an index remapping method, a parameter fetcher fetching suitable timing parameters from the memory in response to a result of the distinguishing by the pattern detector, and a write pulse generator generating the write pulses based on the timing parameters received from the parameter fetcher and information stored in a register.
