Abstract
An apparatus for recording and reproducing data on and from an optical memory has regions for recording data by light only. Code data and image data are processed from a memory within the apparatus. A first retrieval data is added to the code data and a second retrieval data is added to the image data, and the first retrieval data and code data and the second retrieval data and image data are recorded onto an optical memory. Either the first or second retrieval data is designated and depending upon the designation, either the code data corresponding to the first retrieval data or the image data corresponding to the second retrieval data is processed from the optical memory.
