Abstract
A data detection apparatus retrieved binary data modulated in conformity with the (d, k) constraint from an analog signal includes a timing extracting unit for generating a timing signal representing the timing at which the analog signal crosses the threshold value, a clock generating unit for generating a clock signal having a cycle corresponding to one bit of the binary data from the timing signal, a timing position detector for detecting the position in the cycle of the timing, and an error correcting unit for correcting an error in the binary data in accordance with the detected position.
