We report on transport measurements in a Bi-2212 single crystal with columnar defects parallel to the c-axis. The tilt of the magnetic field away from the direction of the tracks is studied for filling factors f=Bz/Bphi<1. Near the Bose Glass transition temperature TBG, the angular scaling laws are verified and we find the field independent critical exponents nu'=1.1 and z'=5.30. Finally, above HperpC we evidence the signature of a smectic-A like vortex phase. These experimental results provide support for the Bose Glass theory.
