Module drive 

The CD drive as the silicon measurements describe it.

Structs

DriveModel

A drive: where the head is, how long a read takes, how long a seek takes.

Enums

Variance

How the run-to-run swing of seek time is modelled. The measured table is one run; the survey reports the true value swinging by about 2x.

Constants

MEASURED_SEEK_MILLIS

Seek time by distance, measured on silicon at double speed: sectors and milliseconds. Survey table; the swing between runs is about 2x.

READ_MICROS_PER_SECTOR_DOUBLE

Microseconds per sector at double speed (6.49 ms), measured on silicon.

READ_MICROS_PER_SECTOR_SINGLE

Microseconds per sector at single speed (13.20 ms), measured on silicon.
