Yeah; I'm imagining the record sits in a basement for 100 years, and has mildew + scratches. Each error correction block has to be (I'd guess) at least 10x wider than a scratch, assuming the codes can correct 1 bit out of 10.

CDs use Reed Solomon, configured for a 1:10000 bit error rate, but NAND storage uses LDPC, which is much more robust.

Anyway, reading such a block would likely take the record player 10's-100's of milliseconds, and xwax seems to target 1ms.
