Document Type and Number:
WIPO Patent Application WO/2023/233952
Kind Code:
A1
Abstract:
The present invention suppresses data fragmentation and minimizes execution of garbage collection. This data recording system comprises a storage (5) and a storage control device (3). The storage (5) has a flash memory (53) having a plurality of blocks (BL) that represent units in which data is erased. Each block (BL) includes a plurality of pages (PA) that represent units in which data is recorded. A controller (55) controls recording of data to the flash memory (53). When data to be recorded can be successively recorded in a set area, the storage control device (3) notifies the set area regarding completion of recording in units equal to the number of recording directives that are needed in order to record the data to be recorded in the set area. When the data to be recorded can no longer be successively recorded in the set area, the set area is notified of an error in recording in units equal to the number of recording directives that are needed in order to record the data to be recorded in the set area.
