Patent ID: 8397136

Claim:
An information recording apparatus, comprising; a writing system for writing datasets to a recording medium, so that each of the datasets can be identified from a certain number indicating an order that each of the datasets was sequentially written to the recording medium, and from the number of writing operations (WP) carried out for a dataset of the certain number; the writing system being configured for appending a second dataset onto a first dataset, the second dataset having the same certain number as the first dataset, and for setting a value obtained by incrementing the WP of the first dataset as the WP of the second dataset; and a writing control system for controlling, in the case where an error occurs at the time of the appending, the appending on the first dataset, in a position shifted forward from the position of the first dataset on the recording medium, and setting the value obtained by incrementing the WP of the first dataset as the WP for the second dataset.
