A UART sets a predetermined threshold remaining data amount n, which defines an interrupt position, in a transmission trigger detector before data transmission is completed, checks if a trigger, which indicates the value of a read pointer RP or a count value N has reached a position indicated by the setting, has occurred and, if the trigger has occurred, causes a trigger detector to output a interrupt output control signal to an internal interrupt circuit to perform internal interrupt processing. Upon detecting this trigger, the internal interrupt circuit outputs an internal interrupt signal. When all data has not yet been transmitted from a transmission FIFO circuit, a CPU of a host controls the amount of data to be transferred to the transmission FIFO circuit, considering the threshold n, to prevent data in that circuit from being overwritten.

A beam shaping and beam splitting device for converting a cross sectional shape of a polarized parallel incident light beam into a light beam having a corrected cross sectional shape, emanating the light beam toward a reflection surface and emanating a return light beam reflected by said reflection surface in a direction which is different from an incident direction of said incident light beam, including a prism made of an anisotropic material and having a first surface upon which said incident light beam is made incident from an incident direction which is inclined with respect to said first surface and a second surface from which the incident light beam emanates from the prism, in which said return light beam is refracted by said first surface and emanates from the first surface in a direction which is different from said incident direction. A separation angle between the incident light beam direction and the emanating direction of the return beam is mainly determined by a difference in the refractive indices of the prism for ordinary and extraordinary rays and can be made very small. In an optical head including such a beam shaping and beam splitting device, the light source and photodetector can be arranged nearer to each other, so that the optical head can be made small in size.

The inward path light emanated from the outward and inward path light separating element is incident on one of these photodiodes, thereby photo-electrically converting the incident light into electrical signals. The inward path light reflected on the one photodiode is incident on the other of the photodiodes, thereby photo-electrically converting the incident light into electrical signals, resulting in acquisition of information signals and servo signals based on these photoelectrically converted signals.

The Wollaston prism is formed by cementing two wedge shaped-crystal plates having different directions of optic axes. The light source and photodetector may be arranged on a same substrate, and thus the optical head can be made small in size and less expensive in cost and can have a high reliability.
