Summary:An optical information storage device having little crosstalk and produced at a low cost. This optical information storage device comprises a circulating data output circuit (14_1) for outputting circulating data including values repeating in units of 5 bytes; and an EXOR circuit (14_2) for operating exclusive ORs (EXOR) recorded data inputted through a buffer (14_5) and the circulating data to input the results of the operation as recording data to a RLL modulation circuit (14_3). Cette invention concerne un dispositif de stockage d'informations optique à faible écho magnétique, produit à bas prix. Ce dispositif comprend un circuit de sortie pour données circulantes (14_1) qui produit de telles données comprenant des valeurs se répétant dans des unités de 5 octets ; et un circuit EXOR (14_2) qui exploite des données exclusives OU entrées via un tampon (14_5) et les données circulantes pour entrer les résultats comme données d'enregistrement dans un circuit de modulation RLL (14_3).
