SONY SMO-F551 LIMDOW
 

MO is designed for applications which require large expandable capacity with fast transfer and/or high speed random access. It is suited for software and multimedia development as well as 'non-linear' audio and video editing. The media is virtually indestructible and particularly useful for image and document storage. Disks are double sided and come in several versions with capacities up to 5.2GB - write once 'Worm' for historical &/or security storage, standard rewritable and high speed 'Limdow'.
