ABSTRACT:
A method and apparatus extract information from a burst cutting area (BCA) of a recording medium. The BCA extraction includes (a) receiving a signal from the recording medium, the signal including BCA data read from the BCA, the BCA data being represented by channel symbols, (b) analog-to-digital (A/D) sampling the signal to generate input data, (c) identifying a BCA region within the input data, the BCA region corresponding to the BCA data, (d) determining an average channel symbol width of the BCA data, the average channel symbol width corresponding to an average number of A/D samples per channel symbol in the BCA data, (e) increasing a signal-to-noise ratio (SNR) of the BCA data using the average channel symbol width, (f) generating a channel pattern data from the BCA data using a selected threshold value, and (g) generating a channel symbol data from the channel pattern data using the average channel symbol width.
