    • A data transfer device that confirms completion of writing into a memory on transferring data to the memory via a bus through which a response indicating completion of data writing in the memory is not sent back includes an inter-memory data transfer control unit performing data transfer between the memories. When the inter-memory data transfer control unit detects switching of a write destination memory from a first memory to a second memory, in order to confirm that writing into the first memory is completed, the inter-memory data transfer control unit performs confirmation of write completion as to the first memory by a procedure different from writing into the memory. When a data transfer with a designated transfer length is completed, in order to confirm that writing is completed as to the write destination memory at the end of the data transfer, the inter-memory data transfer control unit performs confirmation of write completion as to the write destination memory at the end of the transfer by the procedure different from writing into the memory. The inter-memory data transfer control unit notifies the processor of completion of an inter-memory data transfer based on the confirmation of write completion.
    • 一种数据传送装置,其确认写入到存储器中的写入数据经由经由总线的数据传送到存储器,通过该总线不指示在存储器中写入数据的响应的响应不被发回包括存储器间数据传送控制单元, 回忆 当存储器间数据传送控制单元检测从第一存储器到第二存储器的写入目的地存储器的切换时,为了确认对第一存储器的写入完成,存储器间数据传送控制单元执行写入的确认 通过不同于写入内存的过程来完成第一个内存。 当具有指定传送长度的数据传输完成时,为了确认在数据传送结束时关于写入目的地存储器的写入完成,存储器间数据传送控制单元执行关于写入完成的确认 通过与写入存储器不同的过程在传送结束时写入目标存储器。 存储器间数据传送控制单元基于写入完成的确认通知处理器完成存储器间数据传送。

    • An objective optical element for use in an optical pickup apparatus having: a first light source for emitting a first light flux; a second light source for emitting a second light flux; an objective optical element, the objective optical element includes: an optical surface including a common area and an exclusive area; and a wavelength selective film formed on at least one of the common area and the exclusive area; wherein the common area transmits the first light flux which is formed into a converged spot on the information recording surface, and transmits the second light flux which is formed into a converged spot on the information recording surface, and the exclusive area transmits the first light flux which is formed into a converged spot on the information recording surface, and transmits the second light flux which is not formed into a converged spot on the information recording surface.
