*"number of sectors" is used to identify the number of valid entries in the sector information list.
*"sector size" parameter is used to calculate the location of each sector's data. Therefore, The data allocated for each sector must be the same. If the track contains different sized sectors, then the data allocated must be the size of the biggest sector. The "sector size" parameter is used to calculate the location of the sector data. Note that sector size's unit is 256-bytes. So, a sector size of 2, translates to 256 << (2-1), or 512 bytes.
*Sector data always follows Track Information Block at offset &100 from the start of the track information block.
*Sector data is stored in the same order as the sectors in the sector info block.
