    摘要: A recording-medium reproducing apparatus in which different types of recording mediums can be reproduced by the single reproducing apparatus. The apparatus selectively reproduces information from a first recording medium by applying light to an information recording layer through a transparent substrate having a first thickness, and reproduces information from a second recording medium by applying light to an information recording layer through a transparent substrate having a second thickness. The apparatus has a light-generating device for generating light to be applied to the information recording layer of the recording medium. A light-applying device converges the light generated by the light-generating device and applies it to the information recording layer of the recording medium. A light-receiving device, which is divided into a central portion and a peripheral portion, separately receives the light reflected by the recording medium.

    摘要: The present invention provides a memory control device and a semiconductor processing apparatus which can be flexibly made adapted to a plurality of kinds of semiconductor memories. An SDRAM controller has: a register unit to which a command to be issued and a minimum interval (wait time) between issue of the command and issue of the next command are written by a CPU; and a command issuing unit that stops issue of the next command until the minimum interval written in the register elapses since issue of the command written in the register. Therefore, by changing software for the CPU, the SDRAM controller can be flexibly adapted to a plurality of kinds of SDRAMs.
