Colossal Magnetoresistive (CMR) Heads

Now that new giant magnetoresistive (GMR) heads are taking over the market, engineers have turned their attentions to the next breakthrough that will take hard disk read heads to the next level of performance. One of the designs being researched is an evolutionary advance based on GMR that has been dubbed by some as colossal magnetoresistive or CMR. At this stage this technology is in the early stages of investigation, and I have not been able to find much information on it. It would be logical to assume that it involves using slightly different materials than GMR in an effort to further increase sensitivity. When I find more information on CMR I'll add it here.
