Title: Reference clock generation device of sample servo system disk device and disk device
Inventor: YAMADA SHINICHI
IPC: G11B20/12
Filed: 1994-06-20
Abstract: PURPOSE:To make a sample servo system disk device possible to deal with a high density disk reduced in the number of UD area in one track and to move into in a short time into the state where a reference clock signal is stably generated. CONSTITUTION:A unique distance is detected by using output signal of a VCO in the state that a PLL circuit in a timing clock generation circuit 119 is operated based on the output signal of an oscillator 130. When the unique distance is detected, a frequency division ratio of a frequency divider in the PLL circuit is switched, and the PLL circuit is operated based on a clock mark signal (an output of an AND gate 138). Further, the frequency division ratio is set so that the oscillation frequency of the VCO is fixed before and after the output signal of the oscillator 130 is switched to the clock mark signal by a switch 139. Further, the count value of the frequency divider is preset to zero by the first clock mark signal (the output of the AND gate 140) after the unique distance is detected, and thereafter, a clock mark is detected based on the count value of the frequency divider.

Title: Flatness detector
Inventor: KENBOU YUKIO
IPC: G01B11/30
Filed: 1980-10-03
Abstract: PURPOSE:To enable the precise measurement of flatness over the total area, by a method wherein a wafer is irradiated with monochromatic light over a total longitudinal length at a limited lateral width from the surface of a flat transmparent substance placed in the proximity of the surface to be measured to detect an interference fringe, and with this a table is moved in the direction of the lateral width. CONSTITUTION:A flat glass 21 is secured in a manner to have a slight gap between the flat glass and a wafer 6 on a wafer chuck 11, a table 24, which can elongate in a longitudinal direction and move in a lateral direction, is placed  thereon, and a reflection mirror 20 and a linear sensor 22 are mounted at the  opposite ends thereof. The wafer 6 is irradiated with a parallel light from a monochromatic light source, e.g., a laser oscillator, via the reflection mirror 20 and the  flat glass 21. An incident light produces an interference between a reference surface  7 of the flat glass 21 and the surface of the wafer 6, and the linear sensor 22 detects  the interference to indicate a full line in a frame 23 of an after-glowing cathode-ray tube. A motor 25 moves the table 24 from one end to the other end, and a signal  26, synchronizing with the rotation angle of the motor, moves the frame 23 to  observe the whole area. This reduces a size of an optical system and permits the  precise detection over the whole area and building of a detector into an aligner.
