1. The maximum supply ripple is measured at the 5 V input on the drive.
2. The drive shall not incur damage for an over voltage condition of +25% (maximum duration of 20ms) on the 5 V nominal supply.
3. The idle current is specified at 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.
