It consists of a rotating platter coated with a magnetic material. Data is stored on the platter in the form of tiny magnetic domains. The domains can be magnetized in one of two directions, representing the 1s and 0s of binary code.<\/p>\n<p>A magnetic drum is a similar device, but it has a cylindrical shape instead of a flat one. The drum is coated with a magnetic material, and data is stored on the drum in the same way as it is stored on a magnetic disk.<\/p>\n<p>Both magnetic disks and drums are like recirculating shift registers because stored data is available for reading over and over again in the same order. This is because the data is stored on a rotating medium, and the head that reads the data can be moved to any location on the medium.<\/p>\n<p>Options A, B, and C are incorrect because magnetic disks and drums have different storage capacities, their storage is volatile (i.e., it is lost when power is turned off), and their access times are different.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;they have about the same storage capacity&#8221; option2=&#8221;their storage is non volatile&#8221; option3=&#8221;their access times are about the same&#8221; option4=&#8221;stored data is available for reading over and over again in the same order.
