The individual sensors 4, 5, 6 are formed of LED's 8 and photodetectors 9; and the edge of the wafer 1 is detected by a change in their output. The wafer 1 is turned; the sensor 4 detects the edge; and after that, the wafer is turned further and is stopped in such a way that the cutout 2 is passed through the sensors 5, 6. Then, the wafer 1 is moved in the X- direction and the Y-direction; and it is positioned so as to obtain set values to which outputs of the sensors 4, 5, 6 are set. At this time, 1/2 of the sum of an output EON in a light-transmitted state and an output EOFF in a light- shielded state is used as the set values and they are renewed at each wafer 1. Thereby, even when the outputs of the sensors 4, 5, 6 are lowered with the passage of time, a correct positioning operation can be executed.

Title: Information recorder
Inventor: SUZUKI KATSUMI
IPC: G11B7/30
Filed: 1989-06-30
Abstract: PURPOSE:To prevent information to be erased from being left by enlarging a beam spot for erasing rather than a beam spot for recording by using two laser generating means for recording and erasing. CONSTITUTION:A first laser generating means 10 is provided to irradiate on information recording medium 50 with a light beam and to record the information. Then, a second laser generating means 20 is provided to irradiate the medium with the light beam, for which intensity distribution on an irradiated surface is broader than that of the first laser generating means 10, and to erase the information. Namely, since the intensity distribution of the beam for erasing is made broader than that of the beam for recording on the irradiated surface, the erasing spot can be made larger than the recording spot. Thus, it can be canceled to leave the information to be erased.
