Title: Method and device for focus control
Inventor: TAGUCHI AISAKU
IPC: G11B7/09
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To quickly focus jump to an original recording layer prior to the occurrence of the out of focusing condition when an out of focusing occurred during a reproducing/recording of a multilayer optical disk having plural recording layers, to provide proper focusing and to restart reproducing/recording of the original recording layer. SOLUTION: An RF comparator 2 compares the levels of the envelope voltage of RF reproducing signals and a voltage value (a reference voltage VC) corresponding to the lower limit in the vicinity of a focused condition. A jump control section 3 computes the number of jumping over layers of the recording layers based on the frequencies, in which the voltage level of a focus error signal (an FE signal) exceeds the voltage value equivalent to the upper limit of the focused condition, and the frequencies in which the voltage level of the FE signal exceeds the voltage value equivalent to the lower limit of the focused condition.  Then, based on the tilt of the waveforms of the FE signal when discrimination is made and determined that it is in the vicinity of a focused condition by the comparator 2, the direction of the out of focusing is detected and the focus jump is controlled based on the jumping layer number of the recording layers and the out of focusing direction.

Abstract: PURPOSE:To reduce the size of a pulse generator and to enable the generator to accurately read the position of a rotating body by generating pulses by the number equal to the product of the number of permanent magnets and the number of pulse generating elements at every rotation of the rotating body. CONSTITUTION:Permanent magnets 1-4 are arranged on a rotating body 5, with the position of each magnet 1-4 being shifted from another by 90 deg., and pulse generating elements a-c are arranged around the magnets 1-4, with the position of each element a-c being shifted from another by 120 deg.. When the body 5 rotates clockwise by 0 deg. (or 30 deg.), the magnet 1 (or 2) acts on the element (a) (or b) and a first (or second) pulse is generated from the element (a) (or b). When the body 5 further rotates and reaches the position of 60 deg. (or 90'), the magnet 3 (or 4) acts on the element (c) (or a) and a third (or fourth) pulse is generated. Therefore, an initial state cycle is obtained whenever the body 5 rotates by 90 deg. and, when the body 5 makes one rotation, a total of 12 (4X3) pulses are obtained, with the value, 12 being the product of the number of the magnets by that of elements.
