[cctalk] Disk-pack-based drives at LCM

Hi all, I just came across pictures on the LCM website about their SDS Sigma installation there. On the pictures, one can see 10-platter disk packs in the corner and stored on the disk drives. Did the LCM ever had these in operation, either for data retrieval or even demo purposes? I know of the Jim Austin Computer museum where they fixed a CDC 9766 drive but it suffered a head crash after a few hours according to their description which led to giving up the operation of these drives.
