Retro harddrive pics

This history of harddrives is interesting, mostly for the old pics.

The IBM System 305, the world's first computer with a hard drive, debuted in 1956 and relied on the random access method of accounting and control (RAMAC) to store data. This is a side view. The entire device required 50 24-inch diameter platters coated with iron oxide paint mounted on a rotating spindle. It held 5MB, or about 1/100th of the amount in flash cards for cameras today.


And speaking of harddrives, researchers have developed a working prototype of a radical new design based on magnetism rather than transistor.

Because the chip has no wires, its device density and processing power may eventually be much higher than transistor-based devices. And it won't be nearly as power-hungry, which will translate to less heat emission and a cooler future for portable hardware like laptops.

Computers using the magnetic chips would boot up almost instantly. The magnetic chip's memory is nonvolatile, making it impervious to power interruptions, and it retains its data when the device is switched off.
