- 論文の詳細を見る
We developed a new partial-response maximum-likelihood (PRML) detector more suitable for data storage systems than conventional PRML detectors. This detector calculates the likelihood of data sequences from both the direct and the differential partial-response. Therefore, it enables the noise in the likelihood to be made close to white noise. In this paper, we report the mechanism of the new method and the experimental results of applying this method to a 25 Gbyte optical disc playback system.
