Abstract
A memory controller is equipped with a memory data search circuit for carrying out an identifying operation of management information corresponding to a segment located in front of or behind a segment serving as a reference for an editing operation on a recording medium through search and comparison processing of managing information (U-TOC). The system controller does not receive search data and execute the data search but only sets the comparison standard and an initial value and outputs an execution control signal. The editing operation performed, reduces wasted space on a recording medium, such as a disc, and eliminates 'trash areas' which are not addressable in the U-TOC.
