What I'm thinking of is low-level interleaving in the driver or even in the
disk hardware, rather than in the actual file system code. Although around
1978 I wrote a file system that sat on top of the Apple ][ file system, written
in some special version of ALGOL, for a music system my then employer
was building.

The interleaving was done in the interest of access speed, streaming
out audio stuff.
