Abstract
Magnetic recording on a visual image developed by magnetic toner is tried so as to find out the possibility of recording voice and digital data. For comparison with normal magnetic tape, the paper with a toner image is cut to form a 6 mm width tape and set on a deck for open reel tape.
When ordinarily processed, playback output signal by a toner tape is about 40 dB smaller than the signal by a normal magnetic tape. But, by heating to fuse toner particles and by applying magnetic field to orient the magnetic direction of magnetic particles in a toner, the playback output signal becomes larger by 10~20 dB. And the analog signal to 3kHz including manual voice are played back with a noise of 30~40 dB smaller than the signal. And digital data of 25 bit/mm are played back by the speed of 9.5 cm/s ( =2400 baud) and character data in RS232C code are received by computer without any errors. These results show messages or character date can be densely recorded on the toner image of normal toner density.
