Abstract
An information recording-reproducing apparatus comprises a head, a first pair of rollers for guide-driving a recording medium relative to the head, a second pair of rollers for guide-driving the recording medium toward or from the first pair of rollers, and a controller for timingly controlling the first and second pairs of rollers. The first and second pairs of rollers are disposed at such an interval that the recording medium may not be caught by both of the first and second pairs of rollers at a constant velocity movement of the recording medium.
