Abstract
This mechanism has two slot yokes (1,2), two ring-shaped yokes (3,4), four non-magnetic separating sliding blocks (5,6 and 7,8), four permanent magnets (9,10 and 11,12), turning arm (13) with optical head (14), axle (15), counter-balance wt. (16), two cylindrical windings (17,18) and these form four working gaps between the slot yokes (1,2) and magnets (9,10 and 11,12). The permanent magnets are attached to the ring-shaped yokes (3,4) in pairs (9,10) and (11,12) by opposite poles, forming two 'mirror-image' magnetic fluxes.
