In the digital player, a decoder, having at least first and second decoding functions, identifies a type of digital data output from a data storage medium. Based on the identification, the decoder selects one of the first and second decoding functions, and decodes the output digital data using the selected decoding function. A converter converts the decoded digital data to analog. To store digital data on the data storage medium, an encoder encodes a first type of digital data at a first compression rate, and stores the encoded first type of digital data on the data storage medium, which stores digital data of a second type encoded at a second compression rate. The first compression rate is higher than the second compression rate. A selector, having at least a first and second input for the first type of digital data, selectively outputs the first type of digital data received at one of the first and second inputs to the encoder.
