Title: Recording and reproducing device
Inventor: TAKEKADO SHIGERU
IPC: G11B21/08
Filed: 1987-11-05
Abstract: PURPOSE:To attain a high-speed access by moving a transducer to a prescribed position by the detection signal of an optical encoder located in the neighborhood of a driving motor. CONSTITUTION:Since a transducer 6 and a driving coil 11 make an inverted trapezoidal letter shape like an alternate long and short dash line A, a space is large and a large motor for driving can be used. Since an optical encoder 14 of an actuator 9 is very close to a coil 11, when a servo system is constructed, the interval between a driving force and a rotational displacement detecting part to obtain an error signal becomes short, rigidity is improved and therefore, a stable positioning can be attained. By fixing the encoder 14 in the neighborhood of the coil 11, a positioning servo system can be constructed without being influenced by a frequency change. Thus, the high-speed access can be realized.
