ABSTRACT:
If a BS (bad spot) occurs when data is Written, then BST (bad spot table) is updated and registered in an EOD (end of data), thereby making it possible to carry out a recovery operation with ease in a short period of time. A data recorder for recording a DIT (directory information table) on a tape includes a data recorder body (65), a memory means (12) for temporarily memorizing the BST, a write state detecting means (17) for detecting occurrence of BS and a main control circuit (53m) serving as a control means for updating the BST each time BS occurs and controlling the data recorder (65) such that the data recorder (65) records updated DIT of at least the BST on a predetermined position of the tape when the tape is unloaded from the data recorder (65).
