Fedor,
Check out Disk Basic Unravelled for a fairly complete description of the disk structure. 
The OPEN command is used for direct or random access to data files. DSKI$ and DSKO$ are for raw sector access, not files per se. I made good use of random access data files in the Color FOG installer program if you want to study their use. (Also read Color FOG Unravelled to help decipher my code)

Thanks Carl! But how can one find the start or load address?
