Abstract: <P>PROBLEM TO BE SOLVED: To provide an information recording control program executed in a computer for the control of an information recorder and capable of preventing recording to an information recording medium under a recording condition which instabilizes the reproduction of information.  <P>SOLUTION: Data are recorded in the recording area of the information recording medium at a specified recording speed corresponding to a recording request from the outside, and after the recording is ended, a reproducing area inside the recording area where the data are recorded is decided on the basis of the length of the recorded data (step 502). Then, the data recorded in the decided reproducing area are reproduced at a highest speed (step 503), and when it is discriminated that a reproduction error is present (step 505), the recording of the data at the specified recording speed to the information recording medium having the same identification information is inhibited (step 507). Thus, since the recording at the recording speed judged as the one having bad recording quality is inhibited thereafter, the recording to the information recording medium under the recording condition which instabilizes the reproduction of the information is prevented.  <P>COPYRIGHT: (C)2003,JPO
