Abstract: A hydropneumatic positioning device comprises a tu­bular container (10). A hollow piston rod (18) is guided through one end of the tubular container (10). A piston (22) is connected with the piston rod (18) within a cavity (12) of the tubular container. The piston (22) divides the cavity (12) into two working chambers (12a, 12b). The working chambers (12a, 12b) contain a liquid. Adjacent one of the work­ing chambers (12b), namely the working chamber remote from the piston rod (18), a compensating chamber (26) is provided. This compen­sating chamber (26) contains a pressurized gas and is separated from the adjacent working chamber by a floating separating wall (28). A flow passage (24a to 24e) extends through the piston (22) between the two working chambers (12a, 12b). A valve (30) is allocated to the flow pas­sage (24a to 24e). The valve (30) can be opened by an actuating rod (32) extending through an axial bore (34) of the hollow piston rod (18). The actuat­ing rod (32) extends beyond an outer end of the piston rod (18). An actuating signal transformer (11) is fastened to the outer end of the piston rod (18). The signal transformer (11) is constructed as a hydraulic press with a liquid chamber (44), an input piston (56), and an output piston (48). The output piston (48) acts onto the outer end (36) of the actuating rod (32) and the input piston (56) can be actuated manually.

Abstract: A lapping control system for a row of thin film magnetic transducers (12) formed on a substrate (10). Each of the rows comprise a plurality of thin film magnetic transducers and at least two test structures (14, 16). Each test structure has at least two elements which comprises some combination of switch elements (34) or test thin film magnetic transducers (50). As the row of transducers is lapped, each time one of the switch elements is opened, the saturation current (ISAT) of one or more of the thin film magnetic transducers is measured and recorded so that a correlation between ISAT and throat height of the transducers is established during lapp­ing. This correlation is used to establish the point at which lapping should be terminated.
