Head A hard disk has read/write heads which move across the platter. A fully used platter has one read/write head per platter side (2 heads per platter). Sometimes manufactures use only one side of a platter which can result in an uneven number of heads. See also: HDA overview image. Comments? Let us know! ATAREF/2 (C) 2007-2009 WTY Soft.
