Title: Mechanical brake for video disc recording apparatus - with constant braking time and using band and drum technique
Inventor: RICHTER GERD DIPL ING
IPC: G11B19/22
Filed: 1975-06-19
Abstract: The mechanical brake assembly for a video disc recording and playback apparatus is one in which the braking time is almost constant in spite of variations in the friction properties of the brake band and drum. This represents an improvement on existing mechanisms, where the braking time can vary considerably. The mechanism consists of a brake drum (11) mounted on the disc turntable (2) drive shaft (10), around which is wound a brake band (17, 18). One end of this is attached to a spring loaded (21) movable lever (19) and the other end to a spring (15) and through this to the chassis of the appratus. The lever (19) is moved to release the brake during running operations and when a stop is demanded the lever is released so that a constant characteristic braking action under the action of the band spring and lever spring occurs. A constant stopping time is thus achieved.
