James, I was using a fair bit of license with my terminology - There is, in fact, no such thing as -R, or -RW mode
The media is -RW type or +R -R type, according to the type of dye used, with the RW mode needing a laser with at least 3 power levels - read write a '1' and reset back to null '0' state and the -R and +R mode dye requiring only a read power level, and a write a '1' power level The mode of use of the +R and -R media is Write Once - Read Many The hardware expects a continuous flow of data so that the data is written as 1 continuous block of data - as per music on a single track LP ( burn proof methods allow for a break in the data flow, and when the flow resumes after an unexpected break, the write process re-commences after a very small gap, so that the reader can effectively ignore the gap in the dataflow computer data doesn't worry about the gap because data is a series of discrete bits, and your ears and brain ain't good enough to notice the gap in the noise.) Because the -RW media is re-useable, it can be written to as if it were magnetic media - a hard, or floppy drive, That is randomly writing, and changing what was written to the platter in the same mode as a hard drive - sectors (512 byte groups) of data with a gap before, and after each block of data But You can also write to the -RW media as if it were -R or +R media In one continuous stream That is what I mean when I say -R mode and Yes - that is what the main bits of Nero etc. do when they write a 'data', 'music', or 'video' platter and not what InCD does. Oh! and both methods and types of CD and DVD get written in a spiral from the inner edge of the platter while magnetic media are usually written to in a series of concentric circles starting at the outer edge of the media And - just for fun, on a CD, or DVD the data is usually written so that each bit of data occupies a standard area of the disk and that writing process can be with the platter spinning at a constant RPM (CAV) mode, or Constant Linear velocity With the data transfer speed remaining constant under the CLV mode, the spin speed of the platter gets varied With the CAV mode data transfer rate increases so as the heads move out from the centre of the platter, and the effective radius/curcumpherence of the recording 'track'/spiral increases CAV means that the platter can be spun at the maximum rated speed of the platter CLV means that the platter is only spinning at it's rated maximum speed when the heads are at the inner part of the platter so - providing the rest of the system, can keep up, then CAV can be 3 times as fast as CLV because the CLV mode drive ends up spinning the platter at less than 25% of the rated maximum speed.
