Abstract
A multi-format card read/write optical disc drive comprises a micro-controller for processing actions between each component. The micro-controller is connected to a read/write drive, a multi-format card read/write controller, a data codec (coder/decoder), an analog interface transducer, and a computer interface controller. Through the read/write drive and the multi-format card read/write controller, read/write actions are performed to an optical disc and memory cards of various formats, respectively. The data codec is used to decode compressed media data and encode raw data for compression. The analog interface transducer-receives a digital data decoded by the data codec and then converts them into an analog signal for output. The computer interface controller is used to provide connection with a computer for performing bi-directional communications with the computer. The multi-format read/write function of memory cards and optical discs can thus be accomplished, and the added value of the disc drive can also be enhanced.
