Abstract: PURPOSE:To simplify both brake control and clutch switching functions of a take-up reel disk and to miniaturize a magnetic recording/reproducing device, by applying the brake with a pinch roller which is press-contacted to and detached from a capstan in accordance with the working mode of the recording/ reproducing device. CONSTITUTION:In the video record, reproduction and reverse reproduction modes of a VTR, a pinch lever 21 is turned clockwise up to a position where a pinch roller 16 is pressed to a capstan 15. In this case, a kick pin 43 is shifted by a pawl part 21a to turn a coupling gear lever 47 counterclockwise round the center of a rotary support shaft 49. As a result, the engagement is released between a coupling gear 52 and the 1st and 2nd reel gears 4d and 4b. At the same time, a brake gear 50 gears into the gear 4b by means of a spring 51 to perform the brake control. When the operation is switched to a fast forward or rewind mode, the lever 21 is turned counterclockwise. Then a kick pin 42 is shifted by the part 21a, and the gear 52 gears into the gears 4d and 4b. Then the engagement is released between the gears 50 and 4b.

Abstract: PURPOSE:To reduce an amount of side etching at the time of etching, by removing an active layer and a thin second clad layer grown in the first grow process by etching followed by forming the active layer in a buried manner in a photoetching process. CONSTITUTION:A first clad layer C1, an active layer A and a second clad layer C2 having smaller thickness than that of the first clad layer C1 are formed by turns on a substrate S. Next, photoetching is performed while leaving a mesa including a stripe-shaped active layer of fixed width until the first clad layer C1 is reached. Further, the third clad layer C3 is selectively grown in the region removed by photoetching until reaching the top surface of the second clad layer C2 of the said mesa for burying the active layer A in the clad layer.
