In a method of recording actual data of files on a write-once type record medium such as an optical card under the control of file management information including file name and cluster chain management information, the file management information is first read out of a file management information record region of the record medium, cluster chain management information is formed in accordance with the file management information and is stored in a record area which is provided separately from said record medium, and then the actual data of a file is recorded in successive clusters in the data record region of the record medium. Further, a file name and a file length of the file and a head cluster address of the actual data of the file are recorded on the record medium. The cluster chain management information is formed on the basis of file names, file lengths and head cluster addresses read out of the record medium. It is no longer necessary to record the cluster chain management information on the record medium, and therefore the data record region of the record medium can be utilized optimally.
