PURPOSE:To make efficiently analysis etc. of a reproduced data by inserting a sentence such as the content of recorded data, date of recording, condition of recording etc. when recording. CONSTITUTION:When recording, control words (sentence) of maximum 256 characters for superimposing are prepared by the program control of a microprocessor 23 of a system controller 21 using a CRT display 25 and a keyboard 26. The control words are transferred to a memory of a microprocessor 19 through a bus 22, and further transferred to a memory 27 of an interface 5. Transfer to the memory 27 is executed in blanking time of the interface 5, and data transferred by the interruption processing of the microprocessor 19 side. Control words written in the memory 27 of the interface 5 are multiplexed with time so as to come to the forefront of data outputted from a buffer memory 2 and recorded in a magnetic tape. |
