Erasable optical media can be MO (Magneto-Optic) or phase-change. When such erasable media is formatted, every sector on that volume is erased. Then, the directory area is written with all zeroes before the user is told that the format operation is complete. Since this is an extremely resource-consuming process, both in terms of the duration in time and usage of optical devices, it is desired that this not be serial with the workload of the user.
