Title: Laser control circuit of write-in type optical diskdrive
Inventor: SAKANUSHI KATSUHIRO
IPC: G11B7/126
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To speed up the rise of write operation in a write-in type optical disk drive. SOLUTION: A power feeding circuit by Q4 is connected to a control line of Q1 switching a driving current of a laser diode LD, the on/off of Q4 is controlled with Q3 and Q5. As soon as SW1 and SW2 are turned on and SW3 is turned off at the time of write operation, Q3 and Q4 are turned on with a control signal, a control current iR passed through SW1 and collector current iadd of Q4 are charged into the bypass capacitor C of the control line of Q1. When Q1 and Q2 are turned on with the rise of the voltage of C, the driving current iw is made to flow to LD and a write optical pulse is outputted. Also, as soon as Q1 is turned on, Q5 is turned on and Q4 is turned off, and the collector current of Q4 is broken. The charging time of C is reduced and the starting time of Q1 is speeded up by providing with the power feeding circuit.

IPC: H01L21/027
Filed: 1987-09-09
Abstract: PURPOSE:To make X-ray energy contributing to transfer uniform with respect to a sweeping position, by arranging a rotary plate having a specified light screening region, which passes the light path of synchrotron emitted light, between a reflecting mirror and a mask, and differentiating the projecting time rate of the synchrotron emitted light with the sweeping position. CONSTITUTION:A rotary plate 7 is arranged between a thin film 4 and a mask 6. The plate 7 is rotated at a high speed of, e.g., about 100 rotations/sec. A light screening region 8, which is provided in the rotary plate 7, passes the light path of synchrotron emitted light 2 at every rotation. Thus a projection time rate is made different based on a sweeping position. A viewing angle thetafor a chain line 9a along the upper side of a light path range 10 in a non-light- screening region 9 is large. The viewing angle theta for a chain line 9b along the lower side is small. An angle subtending both ends of the chain line 9a viewed from a rotary shaft 7a is made to be alpha. An angle subtending both ends of the chain line 9b is made to be beta. Then, the ratio alpha:beta is made to be, e.g., 100:85 so that the ratio is inversely proportional to the values of the upper and lower sides of the sweeping position in energy E.
