According to the present invention, in the case that the complexity of computation is not increased and only the memory space is doubled, the gain of the received signal in the system is improved effectively, especially when the synchronization of signals is bad, relatively large gain of the signals can be obtained, the system delay is reduced, and the real-time property of signal processing is improved. The method according to the present invention is suitable to the mobile communication system in a bad communication environment.

    摘要： A read/write head and method of making the same are used in a data storage system, such as a disk drive, for perpendicular magnetic recording of data. The head employs a two-layer pole design with a main pole made of sputtered high moment magnetic material, and an adjunct pole made of electroplated soft magnetic film. The main pole is used to write data onto the medium, and is formed over the write coil. The adjunct pole is substantially recessed from the air bearing surface and is formed over the main pole. The present head design significantly enhances the magnetic write field, and substantially reduces side-writing that result in accidental erasure of data in adjacent tracks on the magnetic recording medium.
