Encoding MOD Files Optically On Paper, Because Amiga’s Legacy Will Outlast M-Disks
This technical analysis explores the challenges of storing Amiga MOD files on optical paper, focusing on the limitations of sequential data streams. The author argues that the lack of address labeling makes such storage methods inefficient compared to random-access formats.
Why it matters
Understanding data storage longevity and retrieval efficiency is critical for digital archiving and legacy technology preservation.
Just looking at the photo, I have some severe reservations about the data format. Perhaps it’s equivalent to how data was stored in MOD files themselves, but the change in storage medium might necessitate a commensurate change in formatting.
There doesn’t appear to be any address labeling, or if there is it’s done using marker instructions that have to be interpreted, rather than predictable fixed-size intervals. That seems to imply that seeking within the data stream involves either:
Fragile relative motions (“begin the pattern located N instructions before/after this one”) Absolute addressing relative to some start point (“begin the pattern at instruction X in the file”, or “…starting from marker Y”).
