v The unit houses a no. of non-removable disks.
v It has a motor that rotates the drive at a high contact rate.
v In a Fixed-Head drive, there is usually 1 read/write head for each track on a given surface.
For example, if there are 200 tracks per recording surface, then there will be 200 R/W heads serving each surface, such that, when accessing data, there is no head movement in reading data from one track followed by data from another track. This means that during the Read and Write operations, the R/W heads doesn’t have to move in order to locate the right track because, each track is already located, hence the seek time is zero. This implies that the access time for the disk pack of a fixed head drive is reduced.
v Fixed head drives are more expensive than moving head drives.
