摘要： PURPOSE:To stably reproduce/record information by forming a moving torque providing means with a linear motor including a magnetic circuit comprising a long magnet and long yokes prolonged along the moving direction and engaged with each other and arranging steel-made rollers to the yoke side of the magnetic circuit. CONSTITUTION:A supporting means supporting a pickup body 7 being a holding member holding an objective lens 58 and a servo driving mechanism freely movably along the recording face of a recording medium and the moving torque providing means giving the moving torque to the body 7 are provided. The body 7 consists of supporting rails 5, 6 and steel-made rollers 8, 9 in rolling contact onto the rails and the moving torque provision means consists of the linear motor including the magnetic circuit 28 consisting of the long magnet 16 and the long yokes 17, 18 engaged therewith. The rollers 8, 9 are arranged toward the yokes 17, 18 being almost immune to the magnetic field among the sides of the magnetic circuit 30. Thus, the steel-made rollers 8, 9 are in smooth rolling contact onto the supporting rails 5, 6 and the reproduction/ recording of information is stably attained.

摘要： PURPOSE:To set the optimum value of the recording property when a magnetic tape travles backward, by recording the reference signal after varying one of a record equalizer, bias and level while transporting the magnetic tape in a single direction. CONSTITUTION:During the control of a record equalizer, switches S2a, S2b and S2c are switched to the EQ side to secure the recording mode. Thus a counter 4 of oscillation 1 starts counting and at the same time control signal frequencies f1 and f2 are recorded on a tape 11 for a multivibrator 3. A record equalizer setting circuit 7 controls the level successively and according to the count contents of the counter 4. The recording mode is cancelled by the carry output of the counter 4. At the same time, the tape is controlled backward to secure the reproduction mode. The DC level is obtained for the reproduced signal through a separating circuit 14 and in accordance with the level of f1 and f2 respectively. Then a flip-flop 30 is inverted when a coincidence of the level is obtained through a comparator 17. Thus a switch S1 opens to set EQ. Thereafter, the bias and level are controlled.
摘要翻译：目的：当磁带向一个方向传送磁带时，通过在改变记录均衡器，偏置和电平之一之后记录参考信号来设置记录特性的最佳值。构成：在记录均衡器的控制期间，开关S2a，S2b和S2c切换到EQ侧以确保记录模式。因此，振荡1的计数器4开始计数，并且同时控制信号频率f1和f2被记录在用于多谐振荡器3的磁带11上。记录均衡器设置电路7依次控制电平并根据计数器的计数内容 4.通过计数器4的进位输出取消记录模式。同时，磁带被向后控制以确保再现模式。通过分离电路14分别根据f1和f2的电平为再生信号获得DC电平。然后，当通过比较器17获得电平的一致时，触发器30被反相。因此，开关S1打开以设定EQ。此后，控制偏差和电平。

摘要： PURPOSE:To miniaturize and to lower the cost of a device as a whole, by providing a rocking supporting shaft on the slot side of a supporting member. CONSTITUTION:A clamping mechanism is provided with a pressing member 143 which presses a disk to a turntable, the rocking supporting shaft (shaft 122) extending almost in parallel with the disk carrying plane of the turntable, and the supporting member 140 which is supported by the rocking supporting shaft, and supports the pressing member rotatably freely at a free end part, and the rocking supporting shaft is provided on the slot side of the supporting member. In this way, the space of a corner in a housing can be utilized effectively as the arranging position of the rocking supporting shaft (shaft 122), and a dead space is reduced than ever, and furthermore, the miniaturization of the device as a whole can be easily contrived.
