Title:
パラメータを使用した光ドライブの動作
Document Type and Number:
Japanese Patent JP2008542973
Kind Code:
A
Abstract:
The invention relates to operating an optical drive apparatus from parameters read from an associated record carrier. Data-aided adaptation loops are often used in modern communication and storage systems. To ensure fast and robust start-up by ensuring a stable starting point in an adaptation loop and a fast convergence of the adaptation loop, an information data field is provided on, and read from by the drive, an associated optical record carrier. The information data field comprising start-up parameters, the start-up parameters comprising information about recommended write parameters and information related to a resulting channel response for the case when the recommended write parameters are used. In a start-up situation of the optical drive apparatus, the channel response of the bit detector is computed based on the start-up parameters.
