摘要： A transceiver module for optical communication includes a light-emitting element, a light-receiving element and a rod lens. Light from the light-emitting element is condensed onto the top end of the rod lens. A ferrule of an optical fiber is brought into physical contact with the top end surface of the rod lens so as to couple the light-emitting element and the light-receiving element with the optical fiber. The rod lens is held by a support supported by a spring member on a housing, and the outer diameter of the rod lens is formed so as to be substantially equal to the outer diameter of the ferrule. An opening portion is provided in the housing so that the top end of the ferrule of the optical fiber is slidably fitted into one end of a sleeve, the other end of which is slidably fitted onto the outer circumference of the rod lens. Also, a transceiver module includes a light-emitting element for emitting transmission signal light, a coupling lens for connecting the transmission signal light emitted from the light-emitting element to a light transmission path, and a light-receiving element for receiving detection signal light from the light transmission path, in which the transmission signal light emitted from the light-emitting element is reflected on a surface of the light-receiving element and connected to the light transmission path through the coupling lens; and the detection signal light from the light transmission path is received by the light-receiving element.

摘要： A file is transferred directly between a parent magnetic-disk device and a child magnetic-disk device. In one embodiment, a parent magnetic-disk device has a host-mode execution program, whereas a child magnetic-disk device is capable operating in a device mode as is the case with an ordinary magnetic-disk device. The parent magnetic-disk device has an operating-mode-setting unit including a special-purpose jumper block. An MPU employed in the parent magnetic-disk device executes the host-mode execution program to put the parent magnetic-disk device in a host mode. At an activation time, the MPU refers to the logic of the special jumper block to start an operation in the host mode. The MPU controls the parent magnetic-disk device to directly transfer a file to the child magnetic-disk device. Thus, the file can be transferred between the parent and child magnetic-disk devices without intervention by a host computer.

摘要： A disk drive seek control system device to reduce track pitch. When data is recorded, an offset value is added to the position of a read head element along the width of a track corresponding to an offset &Dgr;w between the read head element and a write head element. The value of the offset depends on the yaw angle &thgr; of the head. When data is read, the position of the read head element is chosen to be either the position of the write head element during write operations, or the midpoint between the position of the write head element and the read head element during write operations, or the center of a track.
