Abstract:
An optical information recording and reproducing method in which there are provided an acceleration region where an optical head is relatively accelerated and moved with respect to a recording track of an optical information recording medium, a first constant-speed region where the optical head is relatively moved at a first constant speed with respect to the optical information recording medium following an end of the acceleration region, and a deceleration region where the optical head is relatively decelerated with respect to the optical information recording medium following an end of the first constant-speed region, wherein the method carries out information recording and reproduction with respect to the recording track while in the first constant-speed region, comprising the steps of:providing a second constant-speed region within at least one of the acceleration region and the deceleration region where the optical head is moved relatively with respect to the optical information recording medium at a second constant speed; andimplementing a jump operation wherein the optical head moves from a first recording and reproduction track to a second recording and reproduction track in the second constant-speed region.
