Pre-compensated optical tape wobble patterns |
摘要 |
<p>Amplitude or phase modulated un-compensated wobble patterns representing address patterns for track addresses of optical media are generated. A filter is applied to the un-compensated wobble patterns to pre-compensate the un-compensated wobble patterns. When an inverse of the filter is applied to a signal representing the pre-compensated wobble patterns in the presence of noise, the noise is suppressed and the un-compensated wobble patterns are substantially recovered.</p> |
