That's not true. A bigger gap doesn't mean the bytes inside sector get

In theory, yes. You can fit 10 sectors into a track if you make the gaps
small enough.
But unless you're doing direct disk I/O, you can't access the 10th sector
in a track. The diskROM

BTW, speaking of disks on PC/MSX...
A disk formatted on MSX usually has a name (of the computer/diskrom)

overwritten by something like IHC). Does anyone know why the PC
overwrites the name?
