摘要： A low cost and highly reliable lubricating technique is realized by using a lubricant having an average molecular weight in the range of 900 to 2500. The lubricant is efficiently supplied to inner portions of a magnetic disk apparatus utilizing heat generated during operation of the apparatus. The method of assembling the apparatus is not affected since it is not necessary to provide a separate lubricant supply mechanism.

摘要： The present invention restricts defect density on the magnetic disk based on predetermined polishing conditions by applying a magnetic field to the entire surface of a magnetic disk in a direction vertical thereto, rotating the magnetic disk, loading a magnetic head to the magnetic disk, reproducing signals from the magnetic disk, processing the reproduced signals by a waveform analyzer, counting pulse waveforms of 0.9 times or more a servo-bit length at ½ threshold value of an average output, and measuring the defect density on the magnetic disk giving an undesired effect on the I/O performance of the magnetic disk drive. In a case of a magnetic recording medium using a vertical magnetic recording system, even with fine defect of magnetic layer, a servo pattern cannot be judged correctly. This provides degradation of the I/O performance of increasing the time necessary for reading out large capacity data, lowering the performance of the entire magnetic disk drive.

摘要： A recording element or a reproducing element in a head generates heat that decomposes lubricating agent adhered to a slider surface near the recording/reproducing element of the head. This decomposed lubricating agent leads to corrosion of the magnetic layer and the like of the magnetic disk. The lubricating agent undergoes volume expansion due to this corrosion, creating a protrusion on the magnetic disk surface to which the lubricating agent is adhered. The magnetic disk surface to which the lubricating agent is adhered comes into contact with the magnetic head, leading to friction with the protective layer, the magnetic layer, and the like. In the worst case, this can lead to secondary errors where data recorded on the magnetic layer is erased. To prevent such secondary errors, the present invention provides a hard disk drive including: a magnetic disk to which is applied a first lubricating agent formed as (where p=0 or an integer of at least 1, q=0 or an integer of at least 1, and X=1-5); and a mechanism for supplying a second lubricating agent to the magnetic disk having an average molecular weight of no more than 2,400 and no less than 600 and formed as HOCH2CF2(OC2F4)p(OCF2)qOCF2CH2OH (where p=0 or an integer of at least 1 and q=0 or an integer of at least 1).
