A seed layer is deposited under an underlayer in magnetic thin film media. The seed layer material has a similar lattice parameter and a similar crystal structure to the underlayer material. The preferred structure involves a nickel-aluminum seed layer, under a chromium underlayer, under a cobalt-based magnetic layer. Use of the nickel-aluminum seed layer produces higher coercivity and lower media noise in the resultant magnetic thin film. The coercivity and media noise values for the resultant magnetic thin film are dependent upon deposition parameters, and recommended deposition parameters are given.
