Computer Generations: Magnetic drum

15.01.2015· The tracks on a magnetic drum are assigned to channels located around the circumference of the drum, forming adjacent circular bands that wind around the drum. A single drum can have up to 200 tracks. As the drum rotates at a speed of up to 3,000 rpm, the device's read/write heads deposit magnetized spots on the drum

01.11.2017· Magnetic drums were the first incarnation of magnetic disk storage. Gustav Taushek, an Austrian inventor, developed the magnetic drum in 1932. The drums read/write heads were designed for each drum track, using a staggered system over the circumference. Without head movement to control, access time is quite short, being based on one revolution of the drum. If multiple heads are used, data
