ABSTRACT:
A thermal printing apparatus for transferring or thermally printing information recorded on a master magnetic tape to a slave magnetic tape which includes a device for detecting or measuring the temperature of the slave tape ahead of the thermal printing process and in which the transport speed of the slave tape and master tape is controlled to accurately control the temperature of the tape. The difference between the temperature of the slave tape ahead of the thermal printing and a reference temperature is utilized to control speed changes and thus achieve optimum thermal printing.
