Abstract
A tape remaining time display method and system is provided for displaying the length of the remaining tape in terms of the length of time. The length of remaining tape is directly or indirectly calculated from a detected cycle for the rotation of the tape supply-side reel. A digital filtering process is performed on the value calculated directly or indirectly from the detected cycle of rotation for the supply-side reel in order to provide a highly accurate tape remaining time display system.
