Abstract
To store data in an insertion process, a processthat inserts data into a new block and a processthat inserts, within the block reserved, data into areas that became free when data was deleted are prepared. A switching event to switch from the processto the processis designated in advance. The occurrence of the designated event is checked while executing the processin an insertion process, and if the designated event occurs, the insertion process executes the process. If during the execution of the process, areas that can be reused become depleted, the execution of the insertion process reverts back to the process. As a result, free areas resulting from deletions can be reused according to the switching event designated.
