RECORDING BODY FOR GUIDING FMTHETA

Japanese Patent JP3705524

B2

PROBLEM TO BE SOLVED: To improve attentiveness and concentration power and to urge the slackening and resting of the mind and the body by making an object listen to the audible sound by providing a track where modulation waves for which a modulation degree is present in the range of a specified % are magnetically or optically recorded and supplying the audible sound including the modulation waves at the time of reproduction.
SOLUTION: All circuits and devices are started, the modulation degree of the modulation waves are adjusted to be above 30-100% while observing a waveform appearing at the output terminal of a modulation wave generation circuit 6 by an oscilloscope, the magnetic tape of a compact cassette type loaded to a magnetic recorder 7 is made to travel at the speed of 4.8 centimeters/second and the modulation waves for which the sine wave whose frequency is about 8 hertz are superimposed on the sine waves whose frequency is above 150 hertz are recorded on the different tracks in the magnetic tape 8. This recording body is provided with the tracks where the since waves whose frequency is about 150 hertz and the modulation waves for which extremely low frequency waves whose frequency is less than about 20 hertz are superimposed on the sine waves are magnetically recorded and the audible sound including the sine waves or the modulation waves are supplied at the time of the reproduction.
