You're right! Copying to a higher-definition medium should in theory allow for effectively lossless copies. There is a potential catch, in that analog copies will tend to introduce some amount of physical errors no matter how much the hypothetical increase in definition should allow for perfection. Subsequent copies, no matter how high their quality, will both tend to amplify these errors and introduce new ones. You get a similar result if you repeatedly re-endcode data even in high-fidelity lossy ways - each encode introduces artifacts and amplifies previous artifacts. It's an intriguing idea! Thank you for bringing it forth for discussion.
