摘要： Embodiments of the invention improve the security of data written on a magnetic disk by performing re-allocation processing starting from a sector whose defect is large in automatic re-allocation processing. According to one embodiment of the present invention, after the reliability of each of data sectors that have been read out from a magnetic disk according to a read command is determined, re-allocation processing on the data sectors is performed in the order of increasing reliability. As a result, within a limited period of time, it is possible to replace by priority a data sector where there is a high possibility that data recovery will be unable to be achieved. This makes it possible to increase the security of data and the reliability of the HDD. The reliability of each data sector is determined on the basis of the number of bytes corrected by ECC.

摘要： An automatic document feeder that is included in an image reader of an image forming apparatus includes a sheet conveying roller, a document feeder cover, a projection piece, a motor, a driving side gear, and a driving force transmission device including an idler gear, a driving force release gear, a slide body, a first elastic body to bias the idler gear and the driving force release gear to be separated, a second elastic body to bias the driving force release gear and the slide body to be separated, and a drive shaft. The driving force transmission device meshes the driving and driven side meshing portions together with a biasing force applied by the second elastic body when the document feeder cover is closed, and releases the driving and driven side meshing portions with a biasing force applied by the first elastic body when the document feeder cover is opened.

摘要： A warning against the possible failure is accurately sent from the magnetic disk device to a host device. In one embodiment, error indices per unit time are stored discontinuously/continuously for each magnetic head, and if the new index (partial integral error rate) updated with the stored multiple error indices as the items to be monitored satisfies required conditions, this state is diagnosed as an abnormality or a pseudo-abnormality, and reported to the host device. The partial integral error rate is updated with an increase in the number of sets of error indices. Each time a new set of error indices per unit time are stored, the oldest of the existing error indices to be monitored is discarded and one of the new error indexes is added. In this way, a new partial integral error rate is calculated from the fixed number of new sets of error indices to be monitored. When the partial integral error rate increases above a second required threshold, this state is reported as an abnormality to the host device since a failure is most likely to occur in the magnetic disk device.

摘要： A liquid discharge apparatus includes a head configured to discharge liquid to print an image on a recording medium according to image data while the liquid discharge apparatus is moved; a sensor configured to detect movement of the liquid discharge apparatus in a predetermined period and output movement information including at least one of a movement amount and an angular velocity of the liquid discharge apparatus; a heater configured to heat the head; a temperature sensor configured to detect a temperature of the head; and circuitry. The circuitry is configured to instruct liquid discharge from the head based on the image data and the movement information from the sensor, detect floating of the liquid discharge apparatus based on a detection result generated by the sensor, and control heating of the head based on a result of detection of the floating.

摘要： Selection of disk drive data tracks for the location of reserved area include providing a media disk with data tracks comprising a user data region. A location is assessed on the media disk with a highest frequency of adjacent track interference and far track interference-refresh potential. The location is then configured to be a reserved area where no user data is written. The reserved area has parameters that are read out first before the disk drive enters an operation enabled state for user interface.
