摘要: A storage device includes a transducer head with multiple write elements having write poles of different sizes. For example, the transducer head may include two write poles of different width configured to write to a same surface of a storage medium. A controller of the storage device is configured to selectively engage one of the multiple write elements to write data to the storage medium.

摘要: A method involves depositing a seed layer comprising at least A1 phase FePt. A main layer of A1 phase FePt is deposited over the seed layer. The main layer includes FePt of a different stoichiometry than the seed layer. The seed and main layers are annealed to convert the A1 phase FePt to L10 phase FePt. The annealing involves heating the substrate prior to depositing at least part of the A1 phase FePt of the main or seed layers.

摘要: In order to improve a consistent data track during writing to a storage medium, a plurality of read sensors are affixed to a transducer head. In one implementation, the transducer head includes multiple read sensors placed up-track of the write pole. In another implementation, the transducer head includes at least one read sensor placed up-track of the write pole and at least one read sensor placed down-track of the write pole. Each position of the multiple read sensors relative to the write pole may be unique. One or more read signals of selected read sensors are used to determine the read location and therefore the write pole location relative to the storage medium.
