INFORMATION REPRODUCTION DEVICE AND INFORMATION REPRODUCTION METHOD |
| 摘要 |
An information reproduction device for use with a magnetic recording medium storing information may include an analog/digital (AD) converter structured to convert an analog signal, which is reproduced from the information recorded in the magnetic recording medium, into a digital signal; a peak detecting unit structured to detect a peak point of the reproduced signal, from the digital signal, according to a threshold as a judgment level in accordance with an output of the AD converter; and an information generating unit for generating structured to generate a rectangular waveform signal of the reproduced signal, waveform-shaped according to interval information of peak points detected by the peak detecting unit. |
