Abstract
The present disclosure describes techniques for DVD-RAM header or land/groove detection. In some aspects, a wobble signal is integrated, an offset is removed from the integrated wobble signal, and a header is detected in the non-offset integrated wobble signal. In some aspects, a threshold value is adjusted based on a comparison of the received wobble signal and the threshold value, and a header is detected based on the adjusted threshold value.
