60539 STC Tape Decks on LEO I
Description of Photograph
Photograph of two STC magnetic tape decks in use in the early stages of LEO I. Rather than being held on a reel, each loop of 1/4 inch tape spooled in a transparent, removeable chamber below the machine's tape heads. The LEO team were unable to get the system to function reliably using tape so the Standard Telephones decks were removed later in the year.
Published in Bird, Peter LEO - The First Business Computer (Wokingham: Hasler, 1994), plate 24.
This image appears in the interactive plan for our Virtual LEO I installation , p47.
Research comments: in the version of this photo in Peter Bird's book, a date can be clearly seen chalked on the right hand unit: 9 July 1953. Interestingly, as the LEO and STC teams could not get these units to work, they were removed just a month after the photo was taken (in August 1953, according to Peter Bird, pp 85). Peter Bird attributes this photo to Leo Fantl, a key member of the LEO team and keen photographer. (LM)
