    摘要: In a method for forming an image, an electrification device electrifies an image bearing member to a predetermined potential. An exposure device exposes the electrified image bearing member. A potential detection device detects the potential of the electrified image bearing member and the image bearing member is re-electrified using the electrification device in accordance with a value obtained on the basis of the detected potential. The potential of the re-electrified image bearing member is detected. A value to be applied to the electrification device is determined on the basis of both the detected potential and the redetected potential when a difference between the redetected potential and a target value is great. An image is formed by electrifying the image bearing member in accordance with the determined value. The image forming method may be used to expose and then reexpose an electrified image bearing member, wherein re-exposure is performed using a drive value of an exposure device obtained on the basis of a detected potential after electrifying the image bearing member when a difference between the detected potential and a target value is great.

    摘要: In an information recording/reproducing apparatus, frame synchronization is speedily performed when initialization is executed or the recording surfaces are switched, and the reliability of recorded data is improved. Segment IDs, each being formed by coding an information word representing a rotational angle measured from a rotational angle origin, are provided within the respective servo areas in such a manner that they are spaced equally in the track direction. While initial synchronization is performed, frame synchronization is established based on the information obtained by decoding the segment ID. This eliminates the need for detecting a home index pattern, thereby speedily performing the initial synchronizing operation. After initial synchronization is achieved, it is constantly monitored whether a frame is not out of synchronization based on the information obtained by decoding the segment ID. When it is detected that a frame is out of synchronization, a suitable operation is performed to minimize the destruction of recorded data.

    摘要: A Viterbi decoder corresponding to PR IV system is composed of an even signal sequence processing circuit and an odd signal sequence processing circuit. A branch metric calculating circuit calculates branch metrics with an amplitude reference level R. In each of expressions for calculating the branch metrics, the number of adding operations is described to one or less. By averaging the number of calculations, the calculation speed of branch metrics can be increased. Thus, the overall process speed of the decoder can be increased. In addition, with a limitation of which the LSB of the reference level R is fixed to "0", the bit width of data to be calculated can be decreased. As a result, the number of adders, registers, and so forth can be decreased.
