摘要： According to the switch of the present invention, a lubricant containing a base oil, a soft resin polymer, and a surface active agent is applied between a fixed tab and a contact strip that undergo sliding operation in response to vertical movement of an operating part. The soft resin polymer of the composition works effective in minimizing wear of the contacting surfaces of the fixed tab and the contact strip. At the same time, including the surface active agent in the composition can prevents the lubricant from flowing to an undesired section. The lubricant with the composition above can provide a switch with a reliable switch-on/off operation.

摘要： Embodiments in accordance with the present invention provide a magnetic disk drive capable of achieving error recovery stably in a simple configuration in the event of thermal asperity (TA) and minimizing the error recovery time required, and a method for controlling the disk drive. According to one embodiment, if TA occurs, a cutoff frequency of a high-pass filter to which a data read signal is input is first increased and a loop gain of a low-order finite impulse response (FIR) filter connected in series to an FIR filter is also increased as high as possible. Next, a Viterbi decoder to which a signal is input from the low-order FIR filter provides feedback to the low-order FIR filter so that an input signal error becomes a minimum. Tap coefficients of the low-order FIR filter are thus optimized.

摘要： A cache-status maintaining unit stores address information of data stored in each entry of a cache memory, and maintains a status of each entry as any one of “strongly modified”, “weakly modified”, “shared”, and “Invalid”. A data-fetching-procedure selecting unit selects, upon receiving a data read request, at least one data fetching procedure based on the address information and the status. A read-data delivering unit selects latest data from among the data fetched, and delivers the latest data to a processor that issued the data read request. A cache-status updating unit updates, when registering the address information of the data, updates the status of the entry based on a type of the data read request.

摘要： Embodiments of the present invention help to detect contact between a head and a magnetic disk more accurately in specifying a heater power value for adjusting a clearance between a head element portion and the disk. According to one embodiment, a hard disk controller/multiprocessing unit (HDC/MPU) measures amplitudes of read signals in a user data field DATA. A hard disk drive (HDD) fills a gap between servo data with single data sector. The HDC/MPU measures the amplitudes of read signals in each data sector at different heater power values. It determines the heater power value at which contact occurs from the measured values.

摘要： An amplifier circuit amplifies the difference between an output voltage from a current voltage conversion circuit and a bias voltage. The current voltage conversion circuit converts a photocurrent of a photodiode which detect incoming light into a voltage. A gm-amp charges or discharges a capacity by a current corresponding to the difference between the output voltage from the amplifier circuit and a reference voltage. A field effect transistor supplies a drain current, which is controlled by voltages at the respective terminals of the capacity, to the photodiode, in order to prevent the output voltage of the amplifier circuit from being varied due to the influence of a DC photocurrent flowing in the photodiode. The gate of a field effect transistor, which is connected in parallel to a current voltage conversion resistor, has an identical voltage with the gate of the field effect transistor.
