摘要:
A method and apparatus for minimizing performance degradation resulting from reassignment of data to alternate sectors as a result of a defect within the original sector. For example, when a request for writing data “a” into a sector A is made but the data is written into an alternative sector A′ in an alternative sector area X because the sector A is defective. Therefore, when a write request for writing data “b” into a sector B is made subsequently, re-assignment is performed to a sector B′ subsequent to the alternative sector A′. Similarly, a defective sector C for which a request for writing data “c” is made is re-assigned an alternative sector C′. Thus, the successive data a, b, and c are written into the successive sectors A′, B′, and C′ in the same alternative sector area X, minimizing performance degradation.

A disk storage device is disclosed for avoiding the instantaneous performance degradation as much as possible, and a method for processing a defective sector in such a disk storage device. There is executed a predetermined check related to a function of the disk storage device, preferably at least one of a read test, a write servo test, or a write test, when the disk storage device is in a waiting state where the disk storage device has no access from a host. The read test and write servo test are used to search for a defective sector on a disk and reassign the defective sector. The write test is used to indicate an abnormal condition of a head. Furthermore, the disk storage device includes a detector for detecting the waiting state, and a check logic for executing a predetermined check.

In the case of magnetic head of magnetoresistance effect type whose breakdown voltage is as low as 0.3 V, it is impractical to ignore even a very small amount of static electricity that occurs during fabrication or use. In one embodiment, the desired magnetic head is produced by forming an SiO2 layer on a silicon slider, thereby forming an SOI substrate; forming on the SOI substrate circuits to protect a TMR element from overvoltage and a read-write circuit; forming field effect transistors from an Si semiconductor layer (formed by reduction of the SiO2 layer or epitaxial growth on the SiO2 layer); forming three electrodes (source, gate, drain) on the Si semiconductor layer; forming a Schottky diode by Schottky contact (metal) with the Si semiconductor layer; forming overvoltage protective circuits of aluminum wiring on the SOI substrate; and forming a TMR element.

The invention provides a golf ball manufactured using a mold having a top half and a bottom half, which ball has formed on a surface thereof, near a seam line corresponding to a parting line between the top and bottom halves of the mold, a recessed and/or raised mark serving as an indicator for detecting the direction or position of the seam line. The invention also provides a golf ball mold composed of a top half and a bottom half that detachably join together so as to form therein a spherical cavity into which a material is injected to mold a golf ball, which mold bears, near a parting line between the top and bottom halves on a wall of the cavity, a raised or recessed feature for forming a mark as an indicator for detecting the direction or position of the parting line. The invention enables the direction and position of the seam line on the surface of the ball to be easily identified and enables the subsequent steps of visually inspecting the ball and applying indicia to the surface of the ball to be carried out more smoothly and advantageously, making it possible in particular to greatly shorten the time devoted to these operations.

摘要:
A task control method by which when a multiprocessor device having processors executes application software tasks, checkpoints have been buried in the application software tasks in advance. In course of execution of each application software task, the checkpoints are used to make an inquiry about passed one of the checkpoints in the task. Then, the progress of each task is judged based on the current passed checkpoint identified as a result of the inquiry and a passed budget corresponding to the passed checkpoint. Based on a result of the judgment, a resource shared by the tasks is controlled, and a new passed budget is set. Thus, the restriction on the scope of application of an application software program is reduced.
