INFORMATION REPRODUCTION DEVICE AND INFORMATION REPRODUCTION METHOD

摘要

This application provides an information reproduction device and an information reproduction method that can be applied to a recording medium with a modulated output without switching the circuit and can suppress the circuit scale and cost increases, and can shorten the read time. An information reproduction device (10) has an AD converter (141) for converting an analog signal that reproduceS the information recorded on a magnetic recording medium (MC) to a digital signal, a peak detector (142) that detects the peak point of the reproduced signal in response to a threshold that is a decision level tracking the output of the AD converter (141) from the digital signal, and an information generation unit (143) for generating a rectangular wave signal of the reproduced signal waveshaped in response to the interval information of the peak point detected by the peak detector.
