Magnetic reproducing and processing device, magnetic recording and reproducing device, and magnetic reproducing method

A magnetic reproducing and processing device, comprising:

• an acquirer configured to acquire a first electric signal obtained by reproducing information recorded in a first recording area of a magnetic recording medium by a first reproducing element and a second electric signal obtained by reproducing the information recorded in the first recording area by a second reproducing element, a first sensitivity of the first reproducing element to a magnetic signal recorded on the magnetic recording medium being different from a second sensitivity of the second reproducing element to the magnetic signal;
• and
• a processor configured to output a reproduced signal corresponding to the information recorded in the first recording area based on the first electric signal and the second electric signal acquired by the acquirer, wherein
• magnetic signal strength includes an nT pattern strength corresponding to n times (n is an integer not less than 3) the minimum recording pattern,
• the first electric signal includes a third pattern signal corresponding to the nT pattern strength,
• the second electric signal includes a fourth pattern signal corresponding to the nT pattern strength, and
• an absolute value of a difference between the strength of the first pattern signal and the strength of the second pattern signal is greater than an absolute value of a difference between a strength of the third pattern signal and a strength of the fourth pattern signal.
