What are Perpendicular Drives?
Perpendicular drives are hard disk storage devices that store data bits vertically rather than “flat” or horizontally. Vertical storage allows for a ten-fold increase in data capacity while preserving data integrity. Traditional hard disks store data bits horizontally on the surface of a platter. To increase drive capacity, bits have been reduced in size to fit more data. However, when bit density becomes too great, the magnetic particles begin to interfere with one another, causing bits to “flip” or reverse orientation. This is referred to as the super para-magnetic effect and results in corrupt or lost data. To overcome this density barrier, perpendicular drives use slightly thicker platters designed to store “embedded” data bits vertically. A head floats over the platter, creating a magnetic field that orients the data bits to an “up” or “down” orientation. For a rough comparison, imagine a bookshelf with a single layer of books laid flat, end-to-end across the shelf. This represent
