Abstract
A method for reading data from a magnetic recording tape having multiple adjacent data tracks according to one embodiment includes simultaneously detecting signals from a plurality of read devices, at least some of the read devices being positioned over multiple data tracks while other of the adjacent read devices are positioned over single data tracks; determining which of the read devices is positioned over a single data track; and simultaneously reading data from the data tracks using only those read devices over the single data tracks. A method for reading and writing data to a magnetic recording tape according to another embodiment includes simultaneously writing data tracks to a magnetic medium; and simultaneously reading the data tracks on the magnetic medium using a plurality of adjacent read devices; wherein the number of the adjacent read devices is at least twice the number of the adjacent write devices.
