摘要： A method of detecting a change in fly-height comprising measuring a first baseline position error signal (PES) at a first diameter on a disk, measuring a second baseline PES at a second diameter, measuring a first transient PES at the first diameter subsequently to the first baseline PES, measuring a second transient PES at the second diameter subsequently to the second baseline PES, determining a first change in PES by comparing the first transient PES to the first baseline PES, determining a second change in PES by comparing the second transient PES to the second baseline PES, performing responsive action when one of the first change in PES exceeds a first threshold and the second change in PES exceeds a second threshold, and generating a general error condition when both the first change in PES and the second change in PES exceed respective thresholds.

摘要： PMR spacing is measured by writing a pattern on a magnetic storage layer in non-return-to-zero notation, reading the pattern from the magnetic storage layer, analyzing a first harmonic component of the pattern that has a first amplitude, analyzing a second harmonic component of the pattern that has a second amplitude, measuring a ratio between the first and the second amplitudes of the first and second harmonic components, and determining a first spacing based on the ratio. In another embodiment, spacing is measured by analyzing a third harmonic component on the magnetic storage layer that has a third amplitude, measuring a difference in the amplitudes of the second and the third harmonic components while varying the first spacing and taking the ratio of the difference of the two each harmonic components.

摘要： A disk drive having a heater element on the read/write head includes control circuitry to prevent head/disk contact by limiting power to the heater element. As the power to the heater element increases, thermal expansion reduces the fly height until head/disk contact occurs. During drive calibration, a maximum power level allowed to the heater element is determined by detecting heater power at a level where a parameter value such as motor current exceeds a threshold level.

摘要： A removable data cartridge is protected from air-transported particles such as dust, excessive moisture, contaminants, and the like by filtering or otherwise conditioning the airflow at initial startup. The recording media in the data cartridge is initially spun at a rate of speed higher than the operating speed for a brief period of time. By spinning the media at the increased speed, any particles in the cartridge will be removed by the filters. After the initial cleaning period, the spin speed of the media is reduced to a normal operating level.

摘要： A head stack assembly is provided for interfacing with a flexible medium of a disk. The head stack assembly includes a first head and a second head located substantially adjacent to the first head wherein the flexible medium may be disposed between the first head and the second head. The first head and the second head are substantially parallel to each other and disposed at a static roll angle θa and a static roll angle θb, respectively, from the flexible medium to impart a curvature to the flexible medium of a disk. The curvature reduces out-of-plane vibrations of the flexible medium and thereby enhances the electrical communicative signal between the flexible medium and the first and the second heads.

摘要： A removable data storage medium for a computer or other data processing device contains at least two data storage disks, a master disk and a backup disk, housed in a single cartridge. All data stored on the device is written to both the master and backup disk. Consequently, the data storage is more reliable because two copies of the data are maintained. The second copy of the data can be used to correct errors or corruption occurring in the first copy, and vice versa.

摘要： A method and apparatus for protecting against overwrite and misread errors caused by cartridge movement comprises a read/write head and a read-write protection switch in electrical communication with the read-write head. The read-write protection switch generates an electrical signal upon movement of the media cartridge that disables the read/write head. A method of misread and overwrite protection comprises: detecting movement of the cartridge shell; disabling read/write heads; identifying whether the media drive was in the process of reading from or writing to the media cartridge; if the media drive was writing to the storage medium when the cartridge shell is moved, generating a write fault interrupt; and if the media drive is reading from the storage medium when the cartridge shell is moved, generating a read fault interrupt. A removable media cartridge has a push member and an abutment surface.
