A method and apparatus for storing and retrieving different types of content relative to an audio CD is described. In one embodiment of the invention, input content of a certain type is converted into converted content of that same type represented by currently unplayable data. The currently unplayable data is Redbook-encoded into data carried in Redbook-encoded format. The data carried in Redbook-encoded format is optically recorded onto a CD. In one embodiment of the invention, data carried in Redbook-encoded format is optically read from a CD. The data carried in Redbook-encoded format is Redbook-decoded into currently unplayable data representing converted content of a certain type, which was converted from input data of the same type. The currently unplayable data is converted into currently playable reconstructed data approximately representing the input content. The input content may be input video content, input audio content sampled at a higher sampling frequency than a sampling frequency allowed by Redbook-encoded format, input audio content sampled with a larger word length than a word length allowed by Redbook-encoded format, etc. |
