Data is stored in circular paths called tracks, which is divided into sectors. The file allocation table (FAT) determines which sector is used. Each disk has 1024 (0 to 1023 tracks); storage begins in the 1023 track moving outward in the disk. A stack (2 or more platters) wil...
Data is stored in circular paths called tracks, which is divided into sectors. The file allocation table (FAT) determines which sector is used. Each disk has 1024 (0 to 1023 tracks); storage begins in the 1023 track moving outward in the disk. A stack (2 or more platters) will have a minimum of 3 sides for data and 1 side for positioning information. Files can become fragmented when the disk is full. NAND cells are preferred over NOR cells because they can be wired in series, which uses less space.
