Abstract: In a recording/reproduction apparatus, when a rotational-speed-mode setting instruction is received from an I/F unit, a CPU reads out a control procedure from a storage device, controlling other components in accordance with the procedure. As a result, a node switch driving circuit controls field windings of a pulse motor to a switching sequence, driving the pulse motor to rotation at a predetermined rotational speed. Since the control is feedback control, the pulse motor rotates at the predetermined rotational speed specified by an instruction setting a rotational-speed mode with a high degree of reliability. Data can thus be recorded into and reproduced from a magnetic disk at a variable speed.

Abstract: A recording and/or reproducing head which is small-sized and lightweight and which does not require focussing servo. In order to achieve this result, a head slider is mounted on a supporting spring movable radially of an optical disc. The head slider includes a base having a recording medium facing surface facing the optical disc, a head unit mounted to the head slider so that an optical recording and/or reproducing head will face the optical disc, a connecting unit for connecting the head unit to the air outlet side of the base, and connecting beams including electro-mechanical transducer elements. The electro-mechanical transducer elements of the beams are driven in response to the supplied driving signals to cause fine movement of the recording and/or reproducing head relative to the optical disc along the tracking direction.

Abstract: A disc-shaped recording medium for which information signals are recorded and/or reproduced in a state in which a rotating recording and/or reproducing head is floated a pre-set distance from a signal recording region carrying surface of the disc-shaped recording medium. The disc-shaped recording medium has an area radially outside of the outer perimeter of center opening by at least 0.1 mm clamped by a clamp mechanism. This area is coplanar as each surface of the disc-shaped recording medium carrying the signal recording region. It is possible in this manner to prevent eccentricity of the rotating disc-shaped recording medium and consequent collision of the recording and/or reproducing head against the disc-shaped recording medium.

Abstract: A floating type head slider used in a disc drive using a disc-shaped recording medium, and adapted to float from the disc-shaped recording medium when the disc-shaped recording medium is rotationally operated. This head slider comprises an air lubricating surface formed on the surface opposite to the disc-shaped recording medium, a taper portion provided at the air inflow end side of the air lubricating surface, a recessed portion of a fixed depth adapted to produce negative pressure, the recessed portion being provided on the center line along the direction from the air inflow end side toward the air outflow end side of the air lubricating surface and being such that the air inflow end side is closed and the air outflow end side is opened, and a groove portion formed along the center line extending from the recessed portion toward the end portion of the air inflow end side of the air lubricating surface, and formed so as to have a width narrower than the recessed portion which divides the air lubricating surface and to have the same depth as that of the recessed portion.This head slider is floated with a fixed floating quantity from the surface of the disc-shaped recording medium in a stable state by positive pressure produced between the air lubricating surface and the surface of the rotationally operated disc-shaped recording medium and negative pressure produced by the recessed portion.
