Abstract:
1. An optical recording device for recording a plurality of data on an optical storage medium, generating a data-interrupt logical address when recording interrupted, and then continuing to reconnect interrupted data from a data-reconnecting physical address so as to enable further correct reading of the interrupted data, the optical recording device comprising: a physical addressing module for providing a reference physical address corresponding to a predetermined physical address on the optical storage medium, as a reference while recording the data on the optical storage medium; a recording-interrupt generator for detecting a recording-interrupt condition, and correspondingly generating a recording-interrupt signal; a data recording controller for recording the data on the optical storage medium, and suspending recording the data on the optical storage medium when receiving the recording-interrupt signal; a data-interrupt logical address generator for generating the data-interrupt logical address when recording interrupted; and a data-reconnecting physical address generator for generating the data-reconnecting physical address according to the data-interrupt logical address, so as to enable the data recording controller, while starting to reconnect the interrupted data, to utilize the data-reconnecting physical address as a starting physical address to record the interrupted data on the optical storage medium; wherein the physical addressing module comprises: a physical address decoder for decoding a physical address detected from the optical storage medium, and generating correspondingly a decoded physical address of the optical storage medium; and a physical address counter set to a value of the decoded physical address and then performing counting according to a reference clock signal and a physical address sync signal to generate the reference physical address, so that the reference physical address is more precise than the decoded physical address.
