View inside a computer hardisk IDE hardrive
A magnetic disk on which you can store computer data The term hard is used to distinguish it from a soft or floppy disk Hard disks hold more data and are faster than floppy disks A hard disk for example can store up to more than 200 gigabytes whereas most floppies have a maximum storage capacity of 1 4 megabytes A single hard disk usually consists of several platters Each platter requires two read write heads one for each side All the read write heads are attached to a single access arm so that they cannot move independently Each platter has the same number of tracks and a track location that cuts across all platters is called a cylinder For example a typical 84 megabyte hard disk might have two platters four sides and 1 053 cylinders In general hard disks are less portable than floppies although it is possible to buy removable hard disks
