Abstract

PURPOSE:To prevent a recording area from being wasted and to free the user from repeating the same operation for a second time. CONSTITUTION:When a new information file and retrieval information on the information file are recorded in the recording area 2 on a card type write-only read-many information recording medium 1 in a rectangular shape by the information recording method which records the information file and retrieval information on the information file on the information recording medium 1, the capacity of the unrecorded area of the recording area 2 is found on the basis of retrieval information which is already recorded and it is decided whether or not the found capacity of the unrecorded area is large enough to record the information file and retrieval information on the information file; when it is decided that the capacity is large enough, the information file and the retrieval information on the information file are recorded.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording method, and more particularly to an information recording method for recording an information file and search information of the information file on a rectangular card-shaped write-once type information recording medium.

[0002]

2. Description of the Related Art A conventional information recording method will be described below with reference to the drawings. FIG. 2 is a plan view of a card-shaped write-once type information recording medium for explaining a conventional information recording method.
As shown in FIG. 2, a card-shaped write-once type information recording medium (hereinafter referred to as a recording medium) 1 has a column-shaped recording area 2, and the recording area 2 includes an information file area 3 for recording information and an information file area 3 for recording information. It is divided into an information search area 4 for searching information in the information file area. Every time information is recorded in the information file area 3 and the information file section 5 is formed, information for searching the information is recorded in the information search area (hereinafter, referred to as a directory area) 4 and the information search is performed. A part (hereinafter referred to as a directory part) 6 is formed. The information file portion 5 is formed from the position B of the divided recording area 2, and the directory portion 6 is formed from the position A of the recording area 2 at the side edge of the recording medium 1.

[0003]

In the conventional information recording method as described above, when recording a new information file and information for searching the information, it is not possible to determine in advance whether additional recording is possible. I didn't go. Therefore, even if additional recording is impossible, a new information file and information for searching the information are recorded. As a result, it is found that additional recording cannot be performed during recording, and not only the recording area is wasted, but also the user has to perform recording again on another recording medium, which complicates the operation twice. There was a problem.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and the recording area is not wasted.
The purpose is to provide a method of recording information that does not require time and effort. And, the above-mentioned object is an information recording method for recording an information file and search information of the information file on a rectangular card-shaped write-once type information recording medium, wherein a new information file and search information for the information file are recorded on the recording medium. When recording, determine the amount of unrecorded area based on the already recorded search information, and whether the amount of the information file to be recorded and the amount of search information of the information file can be stored within the obtained amount of unrecorded area This is achieved by determining whether or not the information file is stored and recording the information file and the search information of the information file.

[0005]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a plan view of a card-shaped write-once type information recording medium for explaining the information recording method of the present invention.
The description of each part of the card-shaped write-once type information recording medium shown in FIG. 1 is the same as that of FIG.

As shown in FIG. 1, the recording of the information file portion 5 is performed from the position C of the recording area 2 at the opposite side edge of the card-shaped write-once type information recording medium (hereinafter referred to as recording medium) 1.
The information retrieval unit (hereinafter referred to as a directory unit) 6 records from the position A of the recording area 2 at the other side edge of the recording medium 1. That is, the recording of the information file and the search information is performed from the recording area 2 at the side end of the recording medium 1 toward the inside. At this time, as a method of additional recording, means for obtaining the amount of the additionally recordable recording area 2 from the directory portion 6 and recording if the additionally recorded information file portion 5 and the directory portion 6 are accommodated therein.

In this case, since the size of the information retrieval area (hereinafter referred to as a directory area) is not fixed, it is possible to reduce waste of the recording area 2 by appropriately performing additional recording. In the above information recording method for the card-shaped write-once type information recording medium, the information file section 5 may be recorded from the position D opposite to the position C of the recording area 2. Further, the information file portion 5 may be recorded from the position A and the directory portion 6 may be recorded from the position C.

In the above information recording method for the card-shaped write-once type information recording medium, the card-shaped write-once type information recording medium in which the recording area 2 is formed in the lateral direction has been described. You may use.

[0009]

As described above, according to the information recording method of the present invention, before the new information file and the search information of the information file are recorded, it is not recorded based on the already recorded search information. Since it is determined whether or not the amount of the area is sufficient for recording, the recording area is not wasted and the user is not forced to do the trouble twice.
