ok merci... Apres recherche sur le net, j'ai trouvé ça:
SST - Headquartered in Japan and Korea, TSST (Toshiba Samsung Storage Technologies) is 51 per cent owned by Toshiba and 49 per cent ownded by Samsung. The TSST joint venture includes product and business planning, product development, procurement and sales for optical disc drives (ODDs), world-wide.
donc ça me rassure une peu.
