摘要:
An information recording/reproducing apparatus removably holding a disk cartridge including a case having a head window and a recording medium stored in the case is provided. The apparatus includes: a rotation mechanism; a cartridge loading mechanism for transporting the disk cartridge from a first unloading position to a first recording/reproducing position when the disk cartridge is mounted, and for transporting the disk cartridge from the first recording/reproducing position to the first unloading position when the disk cartridge is removed; and a head loading mechanism for transporting the head from a second unloading position to a second recording/reproducing position after the disk cartridge has been placed at the first recording/reproducing position when the disk cartridge is mounted, and for transporting the head from the second recording/reproducing position to the second unloading position before the disk cartridge is transported from the first recording/reproducing position to the first unloading position when the disk cartridge is removed. The second unloading position is set outside the periphery of the disk cartridge at the first recording/reproducing position.

A head actuator includes a head slider for carrying a head for recording information to or reproducing information from a recording medium; and a head supporting member for supporting the head slider. The head supporting member includes a substrate and a driving element provided on at least one surface of the substrate for generating an expanding and contracting force in a longitudinal direction in accordance with an external signal, wherein the external signal is applied to the driving element so as to expand or contract the head supporting member in the longitudinal direction and to position the head in a radial direction of the recording medium. The head supporting member includes a first area on which the head slider is provided, a second area on which the driving element is provided, and a third area for connecting the first area and the second area. The driving element has a geometrically central face. The head supporting member has a first neutral face in the second area and a second neutral face in the third area. The second neutral face is on the same side as the geometrically central face with respect to the first neutral face.

The information recording and reproducing apparatus includes: a recording medium including a plurality of concavo-convex pits; a light source for emitting laser light; a section for changing an optical characteristic value of the laser light, using interaction between the laser light and the recording medium; and a light detector for detecting the optical characteristic value of the laser light after the interaction occurs, and then outputting a signal in response to the detected optical characteristic value. The section for changing the optical characteristic value includes an evanescent wave generating section for generating an evanescent wave from the laser light. The evanescent wave generating section changes the optical characteristic value in accordance with how much the concavo-convex pits of the recording medium influences the evanescent wave. Multivalued data is reproduced on the basis of the signal from the light detector. The multivalued data corresponds to the dimension of the concavo-convex pits measured along the direction normal to the recording medium.

Disclosed is a head slider having excellent shock resistance, a head supporter, as well as a disk drive using the head slider. The head slider is characterized in a form of its opposite-to-disk surface, such that a fixed point is set at a position located outwardly of a rear end portion of the head slider and at a predetermined distance from a load application point, which load urges the slider toward a disk. When a shock force is externally applied to the head slider, the head slider is rotated about this fixed point such that at least one of pitch angle and roll angle is maintained positive. Because of this structure, a disk drive excellent in shock resistance can be provided.
