Can my Sony Optiarc play region 1 encoded DVDs?

Can I play Region 1 (USA) coded DVDs with this CD-ROM device? Sony Optiarc DVD-RW AD-7280S

If not,

Is it possible to make it region-free somehow?

The region largely depends on where you bought it from, and is usually visibly marked. The more recent DVD/Blu-ray players have a marking on the back in a globe icon.

As far as I know, there are no region-free Sony players on the market. As for modding it, maybe someone else can shed more light on that.
