​ ghghg The platter (hard disk platter), is one of the pieces that puts the puzzle of the non-volatile hard disk drive together. The function of the hard disk drive is to act as a storage device, and this storage device is only able to do so with the help of the platter. A **hard disk platter** is a circular disk on which magnetic data is stored. Platters can store information and data on both sides, and hard drives usually have several of them mounted on the same spindle. Platters are usually made of aluminum or glass and are coated with a thin layer of coating. Hard drive heads in the hard disk drive fly over the platter in order to extract information and data from them. For this very reason, a platter must be smooth and perfect, because if it isn't, the hard drive will be unable to read the data on the platter and the platter will be useless.
