Abstract:
In a recording controller, an invalidation-request issuing unit, when a second data is recorded on a recording location for a first data that is to be recorded in a memory and a third data corresponding to the second data is recorded in the cache, issues an invalidation request for invalidating the third data, and a notifying unit, when the third data is invalidated, outputs data for identifying a recording request for the first data to an output source of the recording request, and notifies to the output source that recording of the first data is completed.
