US 2006/0077633 A1 · Recording media drive

Abstract

A recording media drive is to be provided in which, when even a voltage capable of being provided in the interior can be provided from the exterior, e.g., the voltage of 3.3V defined in Serial ATA Standard, the voltage can be supplied from the exterior. In one embodiment, a circuit board which controls positioning of a head of an HDD includes a connector connected to an external voltage 5V supply segment and also to an external voltage 12V supply segment, a regulator which generates 3.3V from an external voltage of 5V supplied through the connector, an electronic part capable of being supplied with the 3.3V from the regulator, and a switching control circuit for switching to a voltage supply segment for the supply of 3.3V to the electronic part. In the case where the connector is constructed so as to be connectable to an external voltage 3.3V supply segment for the supply of an external voltage of 3.3V and when it is connected to the external voltage 3.3V supply segment, the switching control circuit performs a switching control so that the external voltage of 3.3V is supplied to the electronic part.
