Title: Double solenoid focus actuator for optical type recorder/reproducer
Inventor: JIESUPAA ESU CHIYANDORAA
IPC: G11B7/09
Filed: 1989-10-26
Abstract: PURPOSE: To achieve a compact, lightweight, and high performance focusing actuator without using a permanent magnet by providing a ferromagnetic member of a low-saturated coercive force and a pair of ferromagnetic elements responding to an electric signal. CONSTITUTION: When operating, radiation reflected from a surface S passes through a beam splitter BS and reaches a detector D. The detector D cooperates with a focus control circuit FC to generate a pair of focus error signals Es and Es' indicating a focal position of a lens. The error signal Es is applied to a coil L2 and Es' is applied to a coil L1 alternately. A coil L1 responds to an error signal Es' and generates a magnetic field which makes a ferromagnetic cylinder member 18 advance in an upward direction, and the magnetic field moves the lens 10 to the surface S. Similarly, a coil L2 responds to an error signal Es and generates a magnetic field which makes the magnetic cylinder material 18 advance downward, and thereby moves the lens 10 off the surface S. Thus, a compact and lightweight focusing actuator is achieved.
