We propose a simple PRML qualification method, calculated from mostly mistakable parts of the played-back signal stream. We confirmed the validity of the qualification method.

A new in-groove format with Saw-Tooth wobble (STW) for blue laser and high NA system is proposed. The STW is designed in order to satisfy for high reliability of the addressing, continuous generation of system clock and easy linking of write data. Th

The possibility of obtaining 50 GB capacity/side has been studied using a blue laser diode, a high-NA objective lens and a dual-layer phase change disk. Using the partial response maximum likelihood method (PRML), which is a superior method of decrea

The partial response maximum-likelihood (PRML) signal processing technique is effective for high-density recording media. However, asymmetry in the playback signal, which is caused not only by inter-symbol interference, but also by mismatched recordi

The partial-response maximum-likelihood (PRML) signal processing technique is effective for high-density recording media. However, there are few omit evaluation methods for qualifying the played-back signal using a simple measurement tool such as a j
