Abstract
A method and device for error analysis particularly adoptable for a recording medium such as an optical disc are disclosed. The present invention executes an encoding-like operation such as an interleaving operation to error flags during reproducing data from the optical disc, so as to obtain number and distribution of the errors on the disc.
Claims11
A method for obtaining error information of an optical disc, comprising:
- receiving error flags corresponding to data recorded on the optical disc, wherein the data is recorded in accordance with a recording sequence;
- writing the error flags to an error buffer in a format of an error flag map;
- reading the error flags from the error buffer according to a sequence corresponding to the recording sequence;
- and
- using the error flags read from the error buffer to obtain information about errors of the optical disc.
