This paper reports an investigation of the structural, magnetic and recording properties of a tri-layer Co80Cr16Ta 4 (2000 Å)/Co3O4 (50 Å)/Pt (100 Å) magnetic thin film. Compared with CoCrTa glass, 50 Å Co3O4 and 100 Å Pt, CoCrTa deposited on the composite Co3O4 (50 Å)/Pt (100 Å) underlayer exhibits strong perpendicular hcp (00.2) crystalline orientation with Δθ50~ 4.1°, fine grains with sub-grain features ~10-40 nm, small S|| ~13%, large room-temperature Hc ~1650 Oe, large R (the ratio between Hc Hc||)~6, and a sharp Hn (perpendicular nucleation field) distribution. Recording measurements performed on the tri-layer film using a thin film tri-pad head showed a pronounced isolated di-pulse in the reproduced waveform, a D50 of ~4500 fr/mm and noise behavior characteristic of a perpendicular medium
