摘要： A disk drive is disclosed that estimates a sinusoidal error in a wedge time period due to eccentricity in the disk rotating to generate eccentricity compensation values. During a write operation a head is positioned over a target data sector within a target track, a write clock frequency is set using an eccentricity compensation value corresponding to the target data sector, and data is written to the target data sector using the write clock frequency. In this manner, the eccentricity compensation value adjusts the write clock frequency to better optimize the linear bit density from the inner to outer diameter tracks.

摘要： The present invention provides a combined vaccine that includes hepatitis B vaccine (HeVac) and Bacille Calmette-Guerin (BCG) for intracutaneous injection and the method of preparation of such vaccine. The combined vaccine changes the now used liquid agent of the HeVac into a cryoprotectant, thus improving the heat stability of the HBsAg. Because of the cryoprotectant in the combined vaccine, the heat stability of the HBsAg is improved, and the efficacy of the vaccine is only slightly decreased after 30 days at 37° C., and the decrease is lower than with the liquid agent of the HeVac. The present invention changes the newborn's inoculation from two injections into one to simultaneously obtain prophylaxis of hepatitis B and tuberculosis.

摘要： Disclosed is disk drive comprising an actuator including a head, a disk having a plurality of tracks, and a processor to control the movement of the actuator and the head relative to the disk. The processor is coupled to the actuator by a flex circuit cable. The processor commands the application of a pre-calibrated bias signal to the actuator during an idle mode to compensate for a bias force imparted by the flex circuit cable upon the actuator such that the head is maintained proximate a pre-determined track of the disk within a pre-determined idle zone of tracks and further determines if a back electromagnetic force (BEMF) reading associated with the actuator is greater than the threshold value, and if so, commands an exit out of the idle mode.

摘要： A method is disclosed for efficiently determining and writing repeatable runout (RRO) compensation value sets for data tracks on a magnetic disk in a disk drive. The disk drive has a magnetoresistive (MR) head having a read element and a separate write element, and a secondary actuator coupled to the end of a primary actuator for adjusting a head skew angle. In the method, the head skew angle is set such that the read and write elements are substantially aligned along the first track. A position error signal for each servo sector is determined over a predetermined number of disk revolutions during track following along a first data track. An RRO compensation value set is calculated for the first data track based on the position error signals. The RRO compensation value set is written for the first data track. A seek operation is then performed to a second data track.
