You state:
In addition there are more sectors in the outside tracks than there are in the innter [sic] tracks.
My understanding of disk sectors has always been that the number of sectors per track is constant for a given disk, and that each sector stores the same amount of data as any other sector.
Because the sectors on the outer tracks cover a bigger surface area on the physical platter, the storage density for those outer tracks is correspondingly lower. The included angle subtended by any sector is the same, which allows the head to read the same amount of data per partial rotation, no matter where on the disk its reading from.
Anyone confirm this?
