ABSTRACT:
A multi-head disk recording and reproducing apparatus, wherein sector synchronization signals obtained from a first optical pick-up and a second optical pick-up are input to a phase comparator where phases are compared, and a preceding sector synchronization signal is output to an overall control unit. In the overall control unit, the processing is carried out with respect to a first optical pick-up and second optical pick-up by a procedure using this input preceding sector synchronization signal as a reference. First, during a term where addresses are determined in the pick-ups, a sled servo and a spindle servo operation are carried out with respect to each pick-up. When the maximum time t of phase deviation has elapsed and addresses are determined, a tracking servo, focus servo, laser control, and other operations are instructed to the control units based on the addresses.
