Check with your PD to see if you did in fact get diversion-- if so, you will not have a conviction on your record. You can probably get the information from the secretary or the front desk, though it may take a while for them to find your case file. The citation will still appear on your no matter what the outcome of the case, as well as the booking.
Either contact the PD's office and ask them, or you might contact the court clerk's office and ask for a copy of your disposition. Also, you can get a copy of your criminal record from the police department (I think the fee is $25 in California).
