Tariq is variant of Taariq and has the exact same meaning and pronunciation (see below for full meaning). You can use either Tariq or Taariq, both are correct and acceptable.

Full Meaning of Tariq:
Tariq means “night visitor” or “star”, since stars appear at night. After the discovery of pulsars, which are highly magnetized, rotating neutron stars that emit powerful beams of electromagnetic radiation, some modern Muslim scholars say that tariq refers to these stars, and this interpretation fits the Quranic verse perfectly, because in Arabic tariq means ‘thing that knocks’, and pulsars were initially called ‘knocking stars’, stars that make a constant knocking sound when listened to on a radio receiver.
