    Abstract: PURPOSE:To improve wear resistance, thermal conductivity, and rigidity and to obtain a magnetic tape cassette of superior sound quality by forming both an upper and a lower cassette half of reacted sintered silicon carbide or reacted sintered silicon nitride. CONSTITUTION:The cassette halves 2 and 3 are molded by injecting a mixture of a mixture of SiC, C, and Si and an added fluidizing agent into an injection mold. This is sintered primarily in a furnace and necessary work is performed when necessary. This molding is sintered in a nonoxidative atmosphere to form the cassette halves 2 and 3. Similarly, reactive sintered silicon nitride is usable. Consequently, the wear resistance, thermal conductivity, and rigidity are improved to obtain the magnetic tape cassette of superior sound quality.

    Abstract: PURPOSE:To cause a cutter head to follow accurately the surface of a lacquer disc and to prevent the modulation of a sound groove accompanied with vibration of a supporting material, by detecting the undulation on the surface of the lacquer disc and the turning speed of the supporting material to control the turning of the supporting material when the sound groove is cut. CONSTITUTION:An undulation detector 24 and a speed detector 27 are turned off, and a depth adjusting current is flowed to an adjusting coil 15 of an electrical and mechanical converter 11 to turn and adjust a supporting material 9, and a cutter needle 8 is set to a reference depth of a sound groove on a lacquer disc 1, and the disc 1 is rotated in a speed lower than the reference speed to cut a cutting lead-in groove on the outside circumference of a disc surface 1a. Next, detectors 24 and 27 are turned on, and a reference position of a cutter head 7 is set, and the disc 1 is rotated in the reference speed to cut the sound groove. At this time, the undulation of the disc surface 1a is always detected to control a coil 16, and thus, the supporting material 9 is caused to follow the undulation; and the turning speed of the supporting material 9 is detected to control a coil 17, and thus, vibration of the supporting material 9 is suppressed.
