摘要： A device for detecting the position of an information recording or reproducing head relative to a recording medium; the head is relatively rotatable around a first axis with respect to the recording medium, and rotatable around a second axis parallel to the first axis. The device includes an autocollimator for measuring a relative positional relationship of the head substantially along the direction of the rotation around the second axis, a rotating table on which either the combination of the recording medium and the head or the autocollimator is mounted to activate the rotational movement substantially around the second axis, and a control unit. The control unit rotates the rotating table in response to the obtained position of the head with respect to the recording medium. According to the measurement result by the autocollimator, the control unit accomplishes a relative positional controlling in which a relative positional relationship between the autocollimator and the head is kept constant. As a result, a compact and high-accuracy head positioning device is achieved.

摘要： A system for the sub-micron positioning of a read/write transducer (28) of a disk drive whereby motion of the transducer, fixed to a transducer holder (30), is caused by a flexing beam (26) deflected by an input spring (32) in turn deflected by an input actuator (34). Motion of the transducer is significantly less than the deflection of the input spring, significantly increasing system resolution while decreasing positioning errors and inaccuracies. The geometry and materials of the flexing beam (26) are such as to promote bending only in a preferred plane parallel to the disk (14) and keep mechanical vibration resonant frequencies higher than the disk rotational frequency.
