CD storage has an interesting take, the available sector size varies by use, i.e. audio or MPEG1 video (VideoCD) at 2352 data octets per sector (with two media level ECCs), actual data at 2048 octets per sector where the extra EDC/ECC can be exposed by reading "raw". I learned this the hard way with VideoPack's malformed VCD images, I wrote a tool to post-process the images to recreate the correct EDC/ECC per sector. Fun fact, ISO9660 stores file metadata simultaneously in big-endian and little form (AFAIR VP used to fluff that up too).

Octets? Don't you mean "bytes"? Or is that word problematic now?

		I wonder if OP used "octets" because physical pattern in the CD used to represent a byte is a sequence of 17 pits and lands. BTW, byte size during the history varied from 4 to 24 bit! Even now, based on interpretation, you can say 16 bit bytes do exist. Char type can be 16 bit on some DSP systems. I was curious, so I checked. Before this comment, I only knew about 7 bit bytes.

		The term octets is pretty common in network protocol RFCs, maybe their vocabulary is biased in the direction of that writing.

		Personally, I prefer the word "bytes", but "octets" is technically more accurate as there are systems that use differently sized bytes. A lot of these are obsolete but there are also current examples, for example in most FPGA that provide SRAM blocks, it's actually arranged as 9, 18 or 36-bit wide with the expectation that you'll use the extra bits for parity or flags of some kind.
