Contact recording disk file with a magnetoresistive read sensor |
| abstract |
A contact magnetic recording rigid disk file utilizes a magnetoresistive (MR) sensor for reading data recorded on the disk. The disk file may be of the liquid-bearing type of contact recording with the MR sensor supported on the trailing end of a carrier which rides on the liquid bearing. The performance of the disk file is enhanced by including means for minimizing the effect of a discovered baseline read signal modulation. The modulation has been determined to be caused by variable cooling of the temperature-sensitive and temperature-elevated MR sensor by the disk, with the temperature variation being directly related to the variation in head-disk spacing caused by the waviness of the surface of the disk. A filter may be incorporated into the read signal processing circuitry of the disk file to eliminate the modulation, the MR sensor may be designed to operate at selected parameters to minimize the effect of the baseline modulation, and the portion of the carrier in contact with the disk surface may be selected to have a length less than the period of the disk waviness so that it more closely follows the disk surface topography. |
