| 摘 要： | The magnetic properties and microstructure of triple C/CoCrTa/Ti perpendicular recording films have been studied. Magnetic measurements show that the optimal thickness of Ti underlayer is 4Ohm and that of CoCrTa is 35 nm. The optimal value of substrate temperature is found to be 400℃. A suitable Ti underlayer causes a magnetic layer to have a near-perfect hcp texture, with Co grains in the （002） preferred orientation. The film with needle-like grains is more suitable for perpendicular recording films. |

| Abstract: | The magnetic properties and microstructure of triple C/CoCrTa/Ti perpendicular recording films have been studied. Magnetic measurementsshow that the optimal thickness of Ti underlayer is 40nm and that of CoCrTa is 35nm. The optimal value of substrate temperature is found to be 400°C. A suitable Ti underlayer causes a magnetic layer to have a near-perfect hcp texture, with Co grains in the (002) preferred orientation. The film with needle-like grains is more suitable for perpendicular recording films. |
