Patent ID: 7581123

Claim:
A recording media drive comprising a recording media drive body; and a circuit board mounted on said recording media drive body, said circuit board comprising: a connector configured to be connected to a first external voltage supply segment for the supply of a first external voltage and capable of being connected to a second external voltage supply segment for the supply of a second external voltage; a second internal voltage supply segment which generates a second internal voltage from the first external voltage supplied through said connector; an external voltage detecting element to detect whether said second external voltage is supplied or not; an electronic part configured to operate at a second voltage; and a switching control circuit which makes control so as to supply said second voltage to said electronic part from either said first external voltage supply segment or said second external voltage supply segment, wherein said switching control circuit makes a switching control so that said second external voltage is supplied to said electronic part upon detecting the connection of said connector to said second external voltage supply segment.
