MAGNETIC STORAGE DEVICE WITH MULTIPLE READ ELEMENT ARRAYS TO DETERMINE QUALITY OF RECORDED DATA

摘要

Determining quality metrics of recorded data on a magnetic recording medium. Each of two or more read element arrays include one or more read elements, each including a sensor. Each array differs from the other arrays in one or more construction characteristics such that each array has a different sensitivity to one or more characteristics of magnetic transitions recorded on a magnetic recording medium. Each array produces respective electrical signals that are characteristic of magnetic transitions recorded on a magnetic recording medium. A computer receives information from the electrical signals and analyzes the signal information to determine one or more values associated with one or more quality metrics of the magnetic transitions.
