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： Embodiments of the invention provide a magnetic disk drive that does not generate errors when information is read even if considerable time has elapsed after the information was written on the magnetic disk. In one embodiment, a magnetic disk has a storage area divided into a plurality of sectors ST1. Time stamps TP1 corresponding to each sector data m1 stored in the sectors ST1 are stored in a time stamp recording medium. A processor controls the magnetic disk drive to read time stamps TP2 of sector data m2 stored in any sectors ST2 of the sectors ST1 and refresh sector data m3 selected based on an elapsed time calculated from information about the time when the time stamps are read and the time stamps TP2.

摘要： Embodiments of the invention prevent offtrack write that will be caused due to a head vibration in a storage device. In one embodiment, a hard disk drive (HDD) judges approval/disapproval of write of user data to a magnetic disk by using a read signal for user data in addition to servo data in write processing. Thus, a head vibration which cannot be precisely detected based on servo data is detected to prevent off-track write. More specifically, the HDD acquires a read back signal amplitude of a read element with respect to a user data sector within adjacent servo data during a write access phase, and detects a vibration from a maximum value MAX and a minimum value MIN of the read back signal amplitude to judge data write approval/disapproval.

摘要： A packing bag is formed by sealing longer side edges, and by sealing V shaped folded sheets to the shorter sides. A portion of the longer side edges is left unsealed to form an inlet port. A protected cylinder or handle may be attached to overlie the inlet port. Opposed notches are formed on both sides of the cylinder or handle to facilitate opening of the bag.
