Recording apparatus for generating write pulse control signals suitable for various types of optical recording media

A recording apparatus for generating write pulses suitable for various optical recording media, the recording apparatus comprising:

• 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 optical recording media using an index remapping method based on lengths of a leading mark (LM), a leading space (LS), a mark (M), a trailing space (TS), and a trailing mark (TS) that are provided by the pattern detector;
• a parameter fetcher fetching timing parameters corresponding to an optical recording medium to which data is to be written 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.
