METHOD AND SYSTEM FOR MANAGING A PULSE WIDTH OF A SIGNAL PULSE

摘要

An input signal is received having a period and an input pulse width. The input pulse width of an in put signal is adjusted to an output pulse width of anoutput signal based upon a recording control signal for control of recording on a storage medium. The output signal and the output pulse width is derived from a triggering edge of a first selected signal of a first selected phase and a triggering edge of a second selected signal of a selected signal of a first selected phase and a triggering edge of a second selected signal of a second selected phase in succession. The first selected signal and the second selected signal are selected from an assortment of reference signals that have distinct relative phases to provide the output pulse width of a desired duration. The number of distinct relative phases available for formation of the output pulse width is increased by one or more of the following: delaying, dividing, inverting, and interpolaiting one or more reference signals.
