摘要： In writing image data having a first size in a memory card (4), a DMA circuit (12) transfers the image data to a memory card controller (6) until the write of the image data having the first size is ended. The memory card controller (6) checks that the state of the memory card is a predetermined state every time the write of image data having a second size smaller than the first size in the memory card (4) is ended and outputs a transfer end interrupt request signal to a CPU (2) in accordance with the end of the write of the image data having the first size in the memory card.

摘要： In an optical information recording/reproducing apparatus capable of executing a first recording method for recording information on either one of a land portion and a groove portion of a recording medium and a second recording method for recording information on both of the land portion and the groove portion, the recording medium is irradiated with a light beam, and a tracking error signal and/or focusing error signal is generated from the reflected light upon irradiation of the light beam. The level of the error signal is compared with a reference level to detect a tracking error state and/or focusing error state. The reference level is adapted to be switched according to the first or second recording method.
