Abstract:
A method for calculating, and displaying on a display apparatus, the writable number of data whose maximum data quantity is no more than the predetermined quantity of a variable length onto a data recording medium, comprising the steps of:counting the number of the data already written onto said data recording medium; obtaining a first value by dividing the whole data capacity of said data recording medium onto which data can be written by said maximum data quantity; obtaining a second value by subtracting the number of data already written onto said data recording medium from said first value; counting the unused data capacity of said data recording medium; obtaining a third value by dividing the unused data capacity of said data recording medium by said maximum data quantity; comparing said second value with said third value; making the smaller value out of said second value and said third value the writable number of the data onto said data recording medium; and displaying on said display apparatus said writable number of the data onto said data recording medium.
