Metals Used in Hard Drives
By Evan Kubitschek
Hard drives are used to store computer data. The technology has been steadily improving, with drives reaching sizes of 2 terabytes. Hard drives are constructed with various metals and alloys.
Hard drives use magnetically charged metals to save data. The magnetic forces manipulate the metals to represent either a 1 or a 0 in binary, which translates into data.
Platters are where the data in a hard drive is stored, and are constructed of aluminum alloy.
The spindle which reads the platters by transmitting a magnetic signal is constructed of copper wire.
Hard drive enclosures that house all the technology are constructed of aluminum.
The screws used to mount the hard drive in a computer are made with steel.
