Abstract

A hand-held optical disc apparatus is configured to playback/record digital audio data and store digital data. The hand-held optical disc apparatus includes a reading module (300), a decoder (320,330), a digital-to-analog converter (340), an analog output, an encoder (220,230), a recording module (250) and a mechanism, adapted to receive an optical disc having a maximum dimension less than 100 mm. The reading module (300) is configured to read the first compressed digital audio data from the optical disc received within the mechanism. The decoder is configured to decode the first compressed digital audio data and generate at least a portion of the first uncompressed digital audio data. The digital-to-analog converter is configured to convert the first uncompressed digital audio data from the decoder to a first analog signal. The analog output is configured to receive the first analog signal. The encoder is configured to receive second uncompressed digital audio data and generate second compressed digital audio data from at least a portion of the second uncompressed digital audio data. The recording module is configured to store the second compressed digital audio data on the optical disc.
