(*1) For detail condition, see Section 4.1.

(*2) Vibration applied to the drive is measured at near the mounting screw hole on the frame as much as possible.

(*3) At random seek write/read and default on retry setting with log sweep vibration.

(*4) At power-off state after installation

Vibration displacement should be less than 2.5 mm.

(*5) Input voltages are specified at the connector.
