What type of magnetoresistance is used in modern hard disk drive?

21 July 2019 1 9K Report

Different types of magnetoresistance effects including giant magnetoresistance (GMR) and tunnel magnetoresistance (TMR) are used for memory technology.

GMR is previously used in the read head of the hard disk dirves.

Has TMR be used commercially in the read head of the HDD, or TMR is only limited to the RAM usage, i.e., magnetic tunnel junction?
