摘要： A flying-type composite magnetic head comprising a slider made of a non-magnetic ceramic and having side rails extending longitudinally on both lateral sides of the head; a slit extending longitudinally in one of the side rails; and a magnetic core. The magnetic core is constituted by a pair of core pieces bonded to each other with a first glass layer and fixed in the slit of the slider with a second glass layer on both sides of the magnetic core. The core pieces have flat opposing surfaces parallel to each other for defining a magnetic gap with at least one of the opposing surfaces formed with an Fe-Al-Si thin layer. The magnetic core is provided in its track surface with a notch for restricting a track width, the notch having a depth equal to or greater than the depth of the magnetic gap, and the remaining thickness of the first glass layer bonding the magnetic core pieces being equal to or greater than the thickness of the magnetic core.

摘要： A multicolor image forming apparatus includes an exposure unit to direct optical beams for optically writing different single-color images on image carriers, respectively, a pattern forming unit to form a positioning pattern on a transport member, a pattern detector to detect the positioning pattern, disposed above the transport member, a positional data detector disposed on a scanning line to detect positional data in a sub-scanning direction of the optical beams, an adjustment unit, and a storage unit. The adjustment unit detects positional deviations among the different single-color images based on detection results generated by both the pattern detector and the positional data detector, respectively, and then corrects the positional deviations. The storage unit stores as reference data the positional data in the sub-scanning direction of the optical beams detected when the positional deviations are corrected.

摘要： A device and method for controlling timing for starting image formation, and image forming apparatus using such device and method are described. A detector outputs a synchronization detection signal when a light beam enters the detector. The timing for starting image formation is determined based on timing when a counter value, which is counted from timing when the synchronization detection signal is detected, reaches a reference counter value. The reference counter value may be determined according to an operation mode.
