PROBLEM TO BE SOLVED: To provide an information recording device capable of performing retrial having a position shifted during overwriting of data set written in a recording medium. SOLUTION: To enable identification based on a writing order number of a data set and the number of writing times (WP) of the data set of the number, data sets are sequentially written in a recording medium. By using a data set written in the recording medium as an old data set, the old data set is substantially overwritten with a data of a new number. A write control means is provided for executing the overwriting means of the old data set by using a value having WP added as a new WP, when an error occurs during overwriting, in a position where the recording medium is shifted forward from the position of the old data set of the recording medium. A predetermined distance is a distance where overwriting of a part of the old data set with a new data set inhibits error correction. COPYRIGHT: (C)2009,JPO&INPIT
