IPC: G11B17/24
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To stop a tray for placing plural disk thereon at the same stopping position by a single detection means. SOLUTION: After the position where the CD tray rotating in the FWD direction is corresponded to the selected placing part, is detected (step 148) by a sensor, the rotating speed of the CD tray is reduced (step 156), and the rotation of the CD tray is stopped (step 160) by detecting (step 158) a stop reference part (arrow A) by the sensor, and also the CD tray is stopped (step 164) after it is rotated (step 162) in the RVS direction for a specified time. Also in the case of rotating in the RVS direction, similarly the CD tray is stopped after the rotation in the RVS direction for a specified time. Consequently, the CD tray is surely stopped at the stopping position with the same amount of error, since the CD tray is stopped by taking the stop reference part as the reference after the rotating direction (RVS direction) of the CD tray is made to the same.

Abstract: PURPOSE:To obtain a semiconductor device which is flat on the surface and small in its area by burying a source/drain region, a gate insulation film, and a gate electrode or its part at least into a semiconductor substrate, and laying out them so that they may conform to the main side of the substrate. CONSTITUTION:A control electrode 7 of a MOS transistor is formed on the surface of a semiconductor substrate 1 so that it may be buried partially or wholly under the surface, thereby forming a channel section 6, where the MOS transistor performs its transistor action, partially or wholly under the surface of the substrate. The control electrode is selectively deposited partially or wholly based on selective chemical vapor reaction so that the surface of the semiconductor device may be flattened. A source (drain) 5, insulation films 2, and 2' and a wiring layer 8 are installed, but they are not limited to this construction. A metal film selection deposition process based on Al or the like is effective to form a control electrode in a groove and hence attain the evenness of the surface of the semiconductor device, which makes it possible to embody a MOS transistor, which is small in its area and flat on the surface. It is, therefore, possible to obtain a high speed and high reliability MOS transistor.
