If reusable data is included in a record of VDP data, a compression level used in compressing page data including the reusable data is associated with the reusable data and stored together with the reusable data. If, after that, a record of VDP data including reusable data similar to the stored reusable data is generated, the page data is compressed according to the record based on the compression ratio associated with the stored reusable data.
