Representative practice, 1984–1994
Observed surface
Hold the rigid shell by its labelled edge.
Keep the shuttered opening clear of fingers, dust, and desk debris.

Implied procedure
Insert once, listen once, and resist the urge to pull the medium during a long seek.
If reading repeats at the same track, record which disk and which file before attempting another copy.
Interpretive residue
The final instruction protects not only data but time already invested in reaching it.
An illuminated lamp converted an invisible write into a temporary prohibition on movement.
