Some neat info about 70s hard drive contaminants.

From the DEC RK05 disk drive maintenance manual (DEC-00-HRK05-C-D)

#retrocomputing #dec

""Relationship of Disk Head, Disk, and Contaminants"

Graph showing a side/cutoff view of hard drive reading head over the platter, with size comparisons:
* Space between the head & platter: 100µ
* Smoke particle: 250µ
* Fingerprint smudge: no unit but it's drawn twice as big as the smoke particle
* Lint & dust: no unit either, 4 times bigger(ish) than the smudge
* Humar hair: .004"

The oxide layer on the disk is 200µ wid
