SD card interfaceing

I am about to put a SD card on my pic, for extended memory, but i realize that the pic is 5v and the SDcard is 3.3V

could i use 2-3diodes in series biased in on each pin(vcc, cs, clk)

and then for data pin put three series diodes bias in to the SD and one diode bias out of SD(parallel to the two in series)

would this work so data in to SD stays under 3v but data out of SD would be over 2v(to trigger ttl pic input)???
 
what kind is that, i could find no references?

everyone on the web is using resistor bridges to reduce the line voltages, and darlington paired transistors to step up the Signal back in
