Who Made/Makes the World Smallest Harddrive

Andy> Probably nothing of smaller capacity in modern days, but much Andy> smaller ones used to exist .... ask PDP8 people about the df32 Andy> disk :-) ...or RC64, on a PDP11... I had RT11 on one of those. Andy> My experience of early hard disks was with the ICT EDS-4 which Andy> stored 4M 6-bit characters (ie about 3 MB) - the (exchangeable) Andy> disk pack was close to the size of a complete PC ... the drives Andy> were referred to as "washing machines" because of their size Andy> and appearance. (and the controller was about the same size Andy> also). The IBM equivalent was, I think, the 1311 ... the 2311 Andy> being equivalent to the ICT EDS-8 (which had twice as many Andy> tracks as the eds4 but was otherwise identical) 1311, indeed. Used one on a 1620. 100 cylinders, 20 sectors per track I think, 100 digits per sector. The head actuator was hydraulic, and once sprang a leak, spraying hydraulic fluid all over the system pack... Andy> Then our PDP11 had an RK05 which was of similar capacity but Andy> somewhat more compact. Much higher... 2.4 MB on just one platter. paul
