Information reproducing apparatus and method, and computer program

An information reproducing method comprising:

• a waveform shaping process of performing waveform shaping on a read signal read from a recording medium, on the basis of a reference amplification factor;
• a correcting process of correcting waveform distortion occurring in a read signal corresponding to at least a long mark, of the read signal on which the waveform shaping is performed in said waveform shaping process;
• and
• a waveform equalizing process of performing a waveform equalization process on the read signal in which the waveform distortion is corrected,
• said waveform shaping process arbitrarily increasing the reference amplification factor.

A computer readable recording medium recording thereon a computer program for reproduction control and for controlling a computer provided in an information reproducing apparatus comprising:

• a waveform shaping device for performing waveform shaping on a read signal read from a recording medium, on the basis of a reference amplification factor;
• a correcting device for correcting waveform distortion occurring in a read signal corresponding to at least a long mark, of the read signal on which the waveform shaping is performed by said waveform shaping device;
• and a waveform equalizing device for performing a waveform equalization process on the read signal in which the waveform distortion is corrected, said waveform shaping device arbitrarily increasing the reference amplification factor,
• said computer program making the computer function as at least one portion of said waveform shaping device, said correcting device, and said waveform equalizing device.
