Abstract
A duplicator system is provided which transfers information signals such as video signals recorded on a mother tape to a copy tape. This duplicator includes a counting system to manage the life of a mother tape. The counting system is operable to count the number of traveling cycles of the mother tape traveling through a preselected tape path and records data indicative thereof on a preselected section of the mother tape. Thus, an operator can easily read out the data indicative of the total number of traveling cycles from the mother tape to confirm the remainder of the working life thereof.
