A tape driving apparatus, and a recording medium, which allows the management of a tape cassette for storing data to be tightened and allows an empty area in a partition to be managed. An initialize count indicating a number of times of initialization of a magnetic tape is defined and is stored in a memory in cassette device of the tape cassette. The initialize count allows the number of times of initialization implemented at least on the magnetic tape of that tape cassette to be grasped. It then becomes possible to estimate a degree of damage of the magnetic tape more accurately by using information capable of indicating a number of times of error, such as Total C3 ECC Retries.
