Claims
- 1. An information recording-reproducing apparatus comprising:
- a head for effecting recording and reproducing;
- first roller means for reciprocally guide-driving a recording medium, which has a length along the reciprocal guide-driving direction, relative to the head;
- second roller means for guide-driving the recording medium toward or from said first roller means by direct contact with the recording medium, said first and second roller means being disposed at an interval longer than said length of the recording medium in the reciprocal guide-driving direction; and
- means for timingly controlling said first and second roller means.
- 2. An information recording-reproducing apparatus according to claim 1, wherein said head is disposed at substantially the same position as said first roller means with respect to the guide-driving direction.
- 3. An information recording-reproducing apparatus according to claim 1, wherein each of said first and second roller means comprises a pair of rollers one of which is timingly controlled by said controlling means.
- 4. An information recording-reproducing apparatus comprising:
- a head;
- first roller means for reciprocally guide-driving a recording medium relative to the head;
- second roller means for guide-driving the recording medium toward or from said first roller means by direct contact with the recording medium, said first and second roller means being disposed at such an interval that the recording medium be caught in direct contact with, and reciprocally moved solely by, said first roller means at the time of recording and reproduction effected by the head; and
- means for timingly controlling said first and second roller means.
- 5. An information recording-reproducing apparatus comprising:
- a head;
- a pair of rollers for reciprocally guide-driving a recording medium relative to the head, the recording medium being reciprocally moved solely by said pair of rollers in direct contact with the recording medium at the time of recording and reproduction effected by said head;
- position sensors provided at opposite ends of a range of movement of the recording medium on either side of said head for effecting reversal timing of the recording medium;
- auto-focusing means for focusing a light beam emitted from said head by driving an objective along its optical axis in said head; and
- auto-tracking means for causing the light beam emitted from said head to follow an information track on the recording medium by driving the objective in a direction orthogonal to the reciprocal guide-driving direction.
- 6. An information recording-reproducing apparatus according to claim 5, wherein said head is positioned in the vicinity of said pair of rollers.
