Yeah, after I posted that I was thinking that it might be confusing. When I used the term "random access memory" what I meant is that RAM and ROM are random access, which they are.
A disc is not random access in the sense that there's a latency between reading sector A and sector B, depending on where they are on the disc.
With RAM and ROM, reading byte A and byte B has the same amount of latency regardless of where the two bytes are in memory; they could be next to each other or at opposite ends of memory.
With a disc it has to wait for the disc to spin the proper sector under the head, and if the sector is on a different track it has to move the head to that track. (I said that backwards; the sequence is that the head first moves to the correct track, then it waits for the proper sector to come round under it.)
