摘要:
A magnetic head is provided for reading and writing data on a data storage media. A first writer and a first reader write and read data of a first format. A second reader reads data of a second format having different read channels than the first format. A third reader has a width greater than that of the of the first and second readers, and reads data of a third format wider than that of the first and second formats. A tape drive is disclosed with the magnetic head and control circuitry having read channels for each of the readers. A method for fabricating a magnetic head is disclosed by providing first and second bumps each with a reader and writer of a first format, and a third bump with a reader of a second format and a reader of a third format.
