In a data recording apparatus capable of recording data while varying the amount of data per unit of time (at a variable rate), the present invention makes it possible to indicate an allowable recording time period on a disc and operational information according to user-specified setup conditions and the remaining capacity of the disc when a user determines conditions for record programming. An allowable recording time period on the disc is calculated on the basis of the remaining capacity of the disc and at least one of the following parameters; a maximum variable-rate value, a minimum variable-rate value, and an average variable-rate value to enable recording video data in most cases. Then, the result of calculation is displayed on a screen. Further, according to user-specified setup conditions including a programmed recording time period and the calculated allowable recording period on the disc, it is determined whether a normal variable-rate recording operation is applicable or an adjusted variable-rate recording operation is required. The result of the determination is displayed on a screen which is so arranged that the user can select either the normal variable-rate recording operation or the adjusted variable-rate recording operation.
