Abstract
An image information recording system reads image information out of a microfilm of which a plurality of image information items are recorded and records it onto a photodisk device. The microfilm has a Blip Mark indicative of the position of a frame. The mark is detected and index information for representing the address of image information recorded on the photodisk device is calculated. In another aspect, the recordable capacity of the photodisk device is sensed. As a result, when one unit of frames of image information is detected to be more than the photodisk device can hold, the one unit of image information is re-recorded on a second recording medium.
