HOLOGRAM MEMORY MEDIUM, APPARATUS AND METHOD OF RECORDING AND/OR REPRODUCING INFORMATION WITH RESPECT TO THE HOLOGRAM MEMORY MEDIUM

摘要

A method of recording/reproducing information on/from a card-shaped hologram memory medium is provided in which an information recording/reproducing optical system can be conveniently controlled to increase a recording capacity of the card-shaped hologram memory medium. In the method, pieces of information are sequentially recorded in a data recording/reproducing area of the card shaped hologram memory medium along a predetermined route, while maintaining a predetermined distance between pieces of information.
