Abstract
In a high speed contact printing system in which a measurement roller is installed to measure the running speed of either a master or slave magnetic tape, the remaining amount or length of the slave magnetic tape wound on a supply reel is automatically and accurately determined on the basis of information as to the thickness of the slave magnetic tape in addition to the rotational speeds of the measurement roller and of the supply reel for the slave magnetic tape. Consequently, the printing system always determines whether one of the programs recorded on the master magnetic tape can be printed on the remaining portion of the slave magnetic tape.
