Reply to comment by oceanwaiting in PsBattle: Man holding a 10 MB hard disk drive platter by AndyJack86

I used to repair these suckers.

Military used them, in the 90s (were still in use in 89 when I left).

Due to the low density of bits, they can survive a EMP blast without corrupting the data.

This particular one is pre 80s and possibly pre 60s. The IBM 2311 platters were smaller than the one shown and dominated the industry. They date back to the 50s. My dad used to store the IBM disks in blue plastic drum containers in the shed and we were told never to “touch them or tell anyone we had them”.

People forget how slow technology used to move. I saw my first CD player in 1984 as a child and it had been out a few years even then.

Oh the systems I worked on were from the 60s, still in operation in the late 80s, still in operation when I departed the location.

It's crazy how old storage mediums were treated, both as a medium and as a standard. I suppose the 'if it aint broke dont fix it' mantra was written in stone.

I heard that the Nasa tapes from the moon landing SSTV tapes were basically erased in the 80s so they could be re-used and only announced in 2009.
