A pilot reported turning left after a CMA Runway 26 departure; because he misread the CMA commercial chart Obstacle Departure Procedure (ODP) which formats the Runway 8 and Runway 26 procedures without sufficient textual separation.

Narrative

Departing from Runway 26 in Camarillo; we were cleared to depart using the published Obstacle Departure Procedure (ODP). I misread the procedure which ends with left turn direct the CMA VOR. This is what we briefed and flew. The procedure requires a right turn to intercept the 265 radial and then left direct the CMA VOR. I have not flown this procedure before and was not familiar. However; in my opinion the core cause of my oversight was twofold. 1) R265 at left edge of chart; I misread as Runway 26. Therefore believed it was the start of ODP for Runway 26 CMA. 2) This turn made sense knowing I was turning away from terrain and housing for noise abatement and toward the normal pattern for the airport. Climbing through 2;000 FT the Controller at Magu asked if we were receiving the Camarillo VOR; which I thought was unusual. This is the only reason I took a second look at the ODP and realized my mistake. I could have easily not caught this mistake. The Controller was not upset; nor did he seem to recognize our error. There was no other traffic or conflict due to early departure before Tower was open in Camarillo. I have a suggestion regarding charting. If each runway that has an ODP was published in its own box; a mistake like this would be harder to make. This won't happen to me again.
