Footnotes:
1
The maximum fixed disk ripple is measured at the 5 volt input of the drive.
2
The disk drive shall not incur damage for an over voltage condition of +25% (maximum duration of
20 ms) on the 5 volt nominal supply.
3
The idle current is specified at an inner track.
4
The read/write current is specified based on three operations of 63 sector read/write per 100 ms.
5
The seek average current is specified based on three operations per 100 ms.
6
The worst case operating current includes motor surge.
