Cross Drilled and slotted rotor question

This is for a 2002 accord V6. My dad recently baught some cross drilled+slotted rotors off ebay for his car. My question is which way are the rotors supposed to face? We mounted them in the manner shown below... Is this the right direction?


Or are they supposed to be mounted this way:

some a desing for the first method and some are for the second!! habitually there stamped R for right side(passenger) and L for left side(driver)

Unfortunately, there are no stamps on these ones telling us which way they go on... On the infinity g35 they are mounted the same as in the first picture (so that they scoop the wind into the disc when the car is going forward) But I've also seen some cars that have them mounted like in the second picture (In order to fling debris and break dust out with centrifigal force) Which of these is considered to be the normal setup? With the first setup it sort of feels like the pads are catching each of the slots as it comes to a stop, is this normal because the pads are new? Or is it not supposed to do this and have them mounted like in the second picture?

anybody?
