GATE CS Original Papers and Official Keys.8 In the magnetic disk, only one disk is accessed at a time. In the optical disk, the data is sequentially accessed. 7 The data in the magnetic disk is randomly accessed. 5 Only one disk can be used at a time Mass replication is possible 6 Tracks in the magnetic disk are generally circular In optical disk the tracks are constructed spirally. MAGNETIC DISK OPTICAL DISK 1 Media type used is Muiltiple fixed disk Media type used is Single removable disk 2 Intermediate signal to noise ratio Excellent signal to noise ratio 3 Sample rate is Low Sample rate is High 4 Implementated where data is randomly accessed. It uses the optical technology in which laser light is centred to the spinning disks.ĭifference Between Magnetic Disk and Optical Disk: It is a computer storage disk that stores data digitally and uses laser beams to read and write data. It is a storage device in which optical (light) energy is used. Random Access Memory (RAM) and Read Only Memory (ROM)Īn optical disk is any computer disk that uses optical storage techniques and technology to read and write data.
