Signal converting device and information recording apparatus employing the same |
摘要 |
<p>In a signal converting device (11) for converting a digital signal (Sr) into a recording signal (Sdd) to be recorded on a storage medium (1), the waveform recognition unit (22) recognizes pulse waveforms of plural kinds in the digital signal, and the storage unit (23) stores recording signal waveforms which are waveforms of the recording signals preset in correspondence with the pulse waveforms of plural kinds. The timing candidate signal generation unit (16) generates a timing candidate signal which is a candidate of a signal indicative of at least one of a rising timing and a falling timing of the recording signal, on the basis of a reference clock signal (Scl) having a period equal to a reference period of the digital signal. The timing signal selection unit (18, 19, 20) selects the timing candidate signal corresponding to at least one of the rising timing and the falling timing as the timing signal (Sld, Str), on the basis of the waveform of the recording signal corresponding to the pulse waveform recognized by the waveform recognition unit. The generation unit (15) for generating the recording signal corresponding to the pulse waveform recognized by the waveform recognition unit on the basis of the timing signal selected by the timing selection unit and the digital signal. <IMAGE></p> |
