ABSTRACT:
In an optical disk recorder which records data in a recordable form in compliance with UDF, when writing of a data block constituting a user data file and a control data file is failed (NO in #2), that data block is rewritten (#5). When the writing of all data constituting the user data file and the control data file is completed (that is, when the writing of the data block constituting the user data file and the control data file is completed) (YES in #3), FE, VAT, and VATICB, which are file management data, respectively, are written (#6). When the writing of the FE, the VAT, and the VATICB are failed (NO in #7), that FE, VAT, and VATICB are rewritten (#8), and when the writing of the FE, VAT, and VATICB is completed (YES in #7), a recording operation is completed. Thereby, even when reproducing the data in the data file from the optical disk in which the writing of the data in the data file is failed, the data in the data file can be reproduced with the rewritten data correctly.
