態が粗となり強度が劣るため実用性がない。[0009] As the waste magnetic tape, such as a video tape, a cassette tape of defective products leaving the plant tape and the tape of spent products (waste) can be utilized. The heat treatment of the waste magnetic tape is performed at a temperature of more than 100 ° C. and 200 ° C. or less, more preferably 140 to 170 ° C. When the temperature is lower than 100 ° C., no curling occurs.
If the temperature is higher than 200 ° C., it is deteriorated by air oxidation and cannot be used. The magnetic tape is cut or crushed to a length of 1 to 50 mm, preferably 3 to 10 mm. If the waste magnetic tape is crushed to less than 1 mm, the crushing becomes too costly and powdery, so that the structure does not have voids inside. If it is larger than 50 mm, the surface state after molding becomes rough and the strength is inferior, so that there is no practicality.
