Media and mass storage

This category is here to show interesting data storage media and devices used to read/write them. It covers both mainframe punched cards and tapes as well as magnetic data streamers and magnetooptical/optical media.
Storing large amounts of data was always a problem. Early mainframe computers had only punched tape/cards permanent memory. To read computation results you had to take the tape and feed it to teletype manually (for example early BESM machines required it). Later units had magnetic tapes allowing to store more data. These computers were built into complex database systems. Punched cards or tapes were used to load programs and data to magnetic tapes.
Later, hard drives became installed in upgraded mainframes. For example in Odra 1305 it was possible to install up to 4 MFM drives (usually IZOT 8MB or Seagate 21MB) per CPU, each one divided to 8MB partitions, each partition addressed as a virtual magnetic tape recorder. Sometimes one tape was usually ELIB (?testy?), a service tape, the other one was programming language or database system. These machines were used in Poland to 2008, as Odra computers serviced properly were very reliable.
As PC compatibles became more and more popular, it was needed to store more and more data for backups or archival purposes. Many companies developed special tape recorders for PC. They used linear or helical system and were capable to store from 20MB to few terabytes (now). Because tape writing is critical about interface speed (you can't easily move the tape back because transmission stopped) these streamers were equipped with fast SCSI bus.
In late 80s or early 1990s, another PC devices came to market: portable data storage. In this page you'll see one of the first "thumb drives" available commercially called PHd (Pocket Harddisk).
