From paper tape to data sticks: The evolution of removable storage

Over the years, people have tried to transfer information from one computer to another in a dizzying number of ways. Here's a look at some of the best, along with others that time forgot.

Data on Tape 



The UNIVAC I (1951) started a new trend in data storage: magnetic tape. IBM soon began using reels of magnetic tape (similar to the audio tape of the time) for computer data storage, and the rest of the industry followed suit. Computer tape, usually stored in open reels, generally consisted of thin strips of plastic coated with a magnetically sensitive substance that computers wrote to and read from by means of electronic heads embedded in a special tape drive.

Numerous production computer models (especially mainframes and minicomputers) used open-reel tape as a mass storage medium until the 1970s and 1980s, when designers switched in increasing numbers to tape cartridges.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
