。In the information recording method of a write-once information recording medium having an information file area for recording information and an information search area for searching information in the information file area as a recording area, the information search area is Is the size arbitrary and the information recording in the information file area and the information search area is of the write-once type? 1! 1 indicates that writing can be started from the opposite side edge of the recording area of the FIN recording medium! The problem is solved by the information recording method of the write-once information recording medium of the present invention using mold.
以下、図面を用いて本発明の実施例について詳
′細に説明する。Examples of the present invention will be described in detail below with reference to the drawings.
'Explain in detail.

るならば記録を行う等の手段を用いる。As shown in FIG. 1, recording in the information file section 5 is performed from position C of the recording area 2 at the opposite side edge of the card-like write-once information recording medium (hereinafter referred to as recording medium) 1. Also, the information search section (hereinafter referred to as directory section) 6 records information at the position A of the recording area 2 at the opposite end of the recording medium l.
Start from That is, recording is performed inward from the recording area 2 at the side edge of the recording medium 1. At this time, the method of additional recording is to read the recording area 2 to be recorded once and record it if it is an unrecorded area, or to perform recording in the directory section 6.
The amount of recording area 2 that can be additionally recorded is determined from the above, and if the information file section 5 and directory section 6 to be additionally recorded fit within that area, recording is performed.
この場合、情報検索領域(以下、ディレクトリ領域と呼
