| 内容記述 | This paper describes the application of Orthogonal Frequency Division Multiplexing (OFDM) method to optical disc recording/readout. OFDM has been widely used in the field of telecommunication owing to its highly efficient frequency usage. However OFDM has not been applied to the optical disc recording because it is a multiple data transfer method and needs to record analog signals. Partial Response Maximum Likelihood (PRML) used in the current optical disc systems requires a certain kind of analog recording. In addition, it is found that the level adjustment of multiple carriers lead to a freedom to adapt the optical disc system characteristics. Using the simple transfer function model of optical disc system, two types of readout signals are calculated and then their qualities are compared. Since Quadrature Amplitude Modulation (QAM) method can be combined with OFDM, it is possible to increase the recoding density of optical disc systems. A method employing OFDM with 64-QAM and the pre-enhance method to the high frequency carrier shows an ability of 1.5 times recording density of the conventional Bru-ray Disc (BD). | |||||||||
