Abstract:
A method and system provide a storage device. A plurality of read sensor stacks for each reader of the storage device are provided. The read sensor stacks are distributed along a down track direction and offset in a cross-track direction. A plurality of electronic lapping guides (ELGs) are provided for the read sensor stacks. The read sensor stacks are lapped. Lapping is terminated based on signal(s) from the ELG(s).
