Title: Rotation detecting device
Inventor: KUBO SHIYOUICHI
IPC: G01P3/487
Filed: 1981-11-05
Abstract: PURPOSE:To obtain the rotation detecting device whose output voltage is not changed even though the rotary speed is changed, by detecting the rotary angle or the number of rotations of a rotor based on the change in resistance values of thin film magnetic resistance elements caused by the magnetic field of a rotation detecting signal magnets. CONSTITUTION:The rotation detecting device is arranged in the vicinity of the signal magnet 4 so as to face it. In this rotation detecting device, a power source E is connected to terminals 9A and 9B of detecting parts 8A and 8B, which are the thin film magnetic resistance elements. A capacitor C is connected to a common terminal 9C. The resistance values of the detecting parts 8A and 8B are changed by the change in the magnetic field which crosses the direction of a current at a right angle. Leaked magnetic field from the main magnets of the rotor acts on the detecting parts 8A and 8B. The detecting parts 8A and 8B are formed with a very close interval in comparison with the arranging interval of the main magnets. Therefore the effect on the detecting parts is approximately the same, and the resistance changes also become the same. Even though the rotor is rotated, the effect of the main magnets does not appear at an output terminal 11. In this way, even though the rotary speed is changed, the output voltage can be made unchangeable.

An output voltage-converted by an optical pickup 2 is converted into a digital signal consisting of the clock signal and the data signal by an analog signal processing circuit 6. An arithmetic means 9 inputs address information and the output of a position sensor 5 to calculate linear velocity at the time of recording. Next, the means 9 operates the transfer rate at the target address and controls a frequency synthesizer 8 to generate the reference clock which is synchronized with or is approximate to the clock signal of a PLL circuit 7 and to extract the clock signal and the data signal. Therefore, a signal processing is executed without depending on the linear velocity.
