Data defect detection using soft decision result |
摘要 |
A defect detection device, apparatus, and method for detecting a defect of data recorded on a recording medium. The defect detection device includes a waveform state detection part generating information representing a state of a waveform of a reproduced signal from the recording medium based on soft decision results obtained in a process of reproducing the data in accordance with a maximum likelihood decoding algorithm corresponding to a partial response. The defect detection device includes a defect determination part determining the defect of the recorded data based on the information generated in the waveform state detection part.
