Dynamic adjustment of disk-drive pickup signals |
摘要 |
Adjustment of disc-drive pickup signals in a manner that responds dynamically to changes in such signals while in use. Adjustment is directed toward achieving an approximately symmetric (i.e., 50-50) duty cycle. A variable integration rate of symmetry error responds to fluctuations in pickup signal frequency to achieve more accurate adjustment of quadrature track crossing signals during a search operation.
