摘要： A magnetic disk which includes a thin film magnetic layer resistant to thermal erasures caused by a rise in localized temperature in the disk due to head disk interference includes a substrate having a thermal diffusivity of less than about 2.times.10.sup.-6 m.sup.2 /sec and a magnetic layer for storing information which is subject to erasure upon such use in localized temperature generated by the head disk interference. An underlayer below the magnetic layer is provided for orienting crystalline structure of the magnetic layer, and the heat sink layer directly above the substrate and directly below the underlayer has a single material such as chromium. The heat sink layer has sufficient thermal diffusivity and sufficient thickness for dissipating heat generated by the rise in localized temperature caused by head disk interference to prevent the erasure of stored information in the magnetic layer.

摘要： A hard disk drive that is capable of inhibiting a write operation when a varying fly height is detected. The disk drive includes a filter circuit that filters a read signal read from a disk. By way of example, the filter circuit may be a low pass filter with a frequency range of 40 to 300 KHz. If the flying height is varying, for example in response to vibration in the drive, the read signal will have a low frequency component. The low pass filter will output the low frequency component. The existence of the low frequency component will cause the disk drive to inhibit a write operation on the disk.
