How high-assurance are these CD destruction methods? I don't recall seeing any articles on CD data recovery under normal conditions, let alone these. As always, it depends on your threat model. (Aside: to me, the only reason for using one-time pads is because you don't trust conventional encryption algorithms. Given that AES is rated for top secret traffic by NSA, I will assert that any enemy who has a chance of attacking it can devote considerable resources to data recovery from smashed CDs.)
