305 RAMAC — прародитель современных жестких дисков

Прародителем современных HDD стал 305 RAMAC от корпорации IBM. Название это расшифровывается как "Random Access Method of Accounting and Control" (Метод случайного доступа к учету и контролю).

305 RAMAC обладал колоссальными размерами, напоминающими промышленный рефрижератор, и весил почти одну тонну — точнее, 970 килограммов. Устройство представляло собой систему из 50 алюминиевых пластин, покрытых ферромагнетиком, каждая из которых имела диаметр 24 дюйма (61 сантиметр).

На тот момент это было настоящее технологическое чудо, несмотря на его внушительные габариты. 305 RAMAC прокладывал путь к современным жестким дискам, которые сегодня можно держать в руке.
