Memory control in recording and/or reproducing apparatus.

摘要

A memory control device having a memory (13) for reading out and holding managing data from a recording medium (1) is equipped with a memory controller (12) for outputting write-in/read-out addresses through an address generating circuit and receiving write-in/read-out data, and a system controller (11) for controlling the memory controller (12) to execute the data write-in/read-out operation on the memory. When link data in the managing information is supplied from the system controller (11) or obtained from the data read in from the memory (13), an address to be next accessed on the basis of the link data is calculated and the calculated address is output to the memory (13).
