Not exactly. The data transferred to the MD recorder via TOSLINK is 1:1 identical to the data on the CD, assuming the read from the CD player is good. Storage on the MD media itself is lossy if ATRAC is in use (there is a lossless MD encoding format though this came very late in MD's lifetime) so going the other way will incur generational loss. This is the same case as if D-VHS uses lossy encoding which I don't know if it does or not.
Point is, the digital data transfer is 1:1.
SCMS stripping does not affect the data at all. It resets the copy count bit and/or the copyright bit in the status subchannel.
