An object of the present invention is to provide a magnetic tape and a magnetic tape cartridge excellent in high recording density characteristics capable of coping with a recording capacity of 1 TB or more. In a coating type magnetic tape, as a magnetic powder to be added to a magnetic layer, a plate-like, granular or elliptical magnetic powder having a number average particle diameter of 5 to 50 nm is used, and the thickness of the magnetic layer is further reduced. It is set to 0.09 μm or less. Further, at least one of the undercoat layer and the back coat layer contains plate-like particles having a number average particle diameter of 10 to 100 nm.
