Raw vs. block device. I'm confused.

I seem to remember a warning once that doing a read on a raw
device reads in at least the physical record size, i.e. sector on disk or
record on tape, regardless of the byte count you put - so that if you have
a 512 byte buffer and read a tape with an 8K block, you write past the
end of buffer!
Is this true? Does it depend on the device controller?
