Titan Disc
Other nos on object: none
Inscription: 105826-3 (centre of disc), SERIAL 1790 (centre of disc),"Data Products Corporation" (centre of disc), "Disc 12 Removed 1/2/71" (handwritten, centre of disc)
Dimensions: 786x786x20
Description: Brown metallic disc with silver metal hub screwed to centre, with a small (75mm diameter) hole in the centre. Disc itself has a number of scratches.
Class: memory
Machine: Titan
Condition: fair, scratched
Notes:
This is a magnetic disk supplied by Data Products for the Titan computer. The entire unit was made of 16 or 32 of these. They utilised moving magnetic heads similarly to today's disk drives. This was the bulk memory for the Titan and it stored quite a large amount of data for the time. It stored data in 512 word blocks like a magnetic tape. Products like this were subject to destructive contamination - if the magnetic head touched the surface it scraped off magnetic particles which then came between the read/write head and the disk and caused more particles to be created, thus leading to the catastrophic destruction of the disk. This happened occasionally. Data Products were an American company who specialised in printers and disk stores.
