Abstract
An information recording-reproducing apparatus includes a holding bed for holding a card-like or sheet-like information recording medium, a head for recording information on the information recording medium or reproducing the information recorded on the information recording medium, a device for reciprocally rectilinearly moving the holding bed relative to the head, and a device operatively associated with the movement of the holding bed, reciprocally moving a body of a predetermined weight. The device prevents shock during the reversal of the holding bed.
Claims17
An information recording-reproducing apparatus comprising:
- first holding means for holding a card-like or sheet-like information recording medium;
- a first head for recording information on said information recording medium or reproducing the information recorded on said information recording medium held by said first holding means;
- first means for reciprocally rectilinearly moving said first holding means relative to said head;
- second holding means for holding a card-like or sheet-like information recording medium;
- and
- second means for reciprocally moving said second holding means in a direction parallel with and opposite to the direction of movement of said first holding means, said second holding means being operatively associated with the movement of said first holding means.
An optical information recording-reproducing apparatus comprising:
- holding means for holding a card-like or sheet-like optical information recording medium, said recording medium having a linearly-extending track;
- an optical head for optically recording information on the optical information recording medium or reproducing the information recorded on the optical information recording medium, said optical head including an objective which is controlled so as to be placed at an optimum position with respect to both a focus direction of said objective and at track direction of the track travelled by the recording medium;
- first means for reciprocally rectilinearly moving said holding means relative to said optical head in a track extending direction while said objective of said optical head is controlled so as to be placed at said optimum position, said optical head being stationary with respect to the track extending direction;
- and
- second means for reciprocally moving a body of a predetermined weight in association with the movement of said holding means, with said second means preventing shock during the reversal of said holding means, said objective being controlled so as to be placed at said optimum position during reversal of said holding means.
