Disk Scheduling

Disk Scheduling. Disk Structure. Points to consider: Sector sizes (number of bits per sector) should be fixed. The density of the magnetic material is constant on the surface of the disk. Size of the sector gets smaller as the radius of the track gets smaller. direction of rotation. sector.
