- Typically an Atari disk will contain 40 'tracks'.

Feb 18, 2024 · If the disk is single or double density, it has 18 sectors per track, and the physical track and sector numbers are (vsec-1)/18 and (vsec-1)%18+1. If it is enhanced density, it's (vsec-1)/26 and (vsec-1)%26+1.
40 tracks x 18 sectors/track = 720 sectors/disk. 720 sectors x 256 bytes/sector = 184,320 bytes/disk (180KiB) - While most 815 sample drives utilized the same Tandon drive mechanism found. in late-production Atari 810 drives, there were also 815 sample drives built.
The new Atari format uses 26 sectors per track instead of 18, which gives the 1050 about 127K bytes of formatted storage in this mode. This compares to 176K for true double density, and 88K for single density.
Each or the 40 tracks contain 18 sectors for a total of 720 sectors per disk. Sectors 1 through 18 use the outermost track, while sectors 712 through 720 use the innermost. When a disk is being formatted, the head will move sequentially through the tracks, reorganizing the sectors.
Atari ST disks are standard MFM encoded IBM scheme disks without an IAM header. Disks are typically formatted 512 bytes per sector with between 9-10 (sometimes 11!) sectors per track and 80-82 tracks per side.

What is a real Atari disk?
The disk is divided into 80 concentric circles called "tracks", which are numbered from zero at the outside to 79 near the center. Each track is divided into nine "sectors" numbered from one to nine, giving the disk a total of 720 sectors. And each sector can hold 512 bytes of information.
