Embodiment Construction

[0051] Now, preferred embodiments of the present invention will be described in detail, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0052] Figure 6 and 7 The operating theory of the actuator of the optical pick-up device will be described. Figure 6 Indicates the direction of rotation, while Figure 7 Explain the Lorentz force.

[0053] Rotations about the X, Y and Z-axes are called pitching, rolling and yawing, respectively.

[0054] as in Figure 7 As shown in , the force applied to the actuator is generated by the combination of the magnetic field formed by the permanent magnet and the current flowing along the coil.

[0055] Figure 8 and 9 An actuator for driving an optical pickup device in an optical read / write device according to an embodiment of the present invention will be described.

[0056] As shown in the figure, th...

Abstract

An optical writing and reading device includes: a base; a main shaft holder fixed to the base; a main shaft supported by the main shaft holder; a pickup base supported by and moving along the main shaft; an optical pick-up actuator formed at the pickup base; an optical system for emitting and receiving a light to and from the optical pick-up actuator to write or read data on or from an optical disk; and a turntable and a spindle motor for rotating the optical disk.

Description

technical field [0001] The present invention relates to an optical read / write device for writing data on or reading data from an optical disc. Background technique [0002] Typically, optical read / write devices are used in computers, digital video disc (DVD) players, and similar devices to write to and read from optical discs, such as compact discs, digital video discs, Blu-ray discs, etc. data. [0003] In recent years, digital devices such as laptop computers, camcorders, and digital cameras have been reduced in weight and size, so that miniaturization of data storage media has become necessary. [0004] In particular, the application of optical discs to mobile devices such as mobile phones and personal digital assistants (PDAs) has been continuously studied. In order to apply optical discs to such mobile devices, there is an urgent need to miniaturize the size of the optical pickup device. [0005] The reduction in the size of the optical pickup device has been limited...
