    摘要： An information recording/reproducing apparatus wherein the CPU stores data transferred through an interface in a temporary storage area and later records the data in a recording medium by using a recording/reproducing means. The temporary storage area is divided into first and a second regions by a temporary storage region disposition device. A discriminator determines whether the process-requested region is an information managing region or a data region from the process requests made by the host computer and the temporary storage region managing information. Based on the result of this discrimination, the temporary storage region manager allocates the first region if the data is for information managing or the second region if the data is intended for data storage.

    摘要： An information recording reproducing apparatus is operable with a large-capacity recording medium and is operatively connected to a host computer. The apparatus has a cache memory for temporarily storing therein information transmitted from the host computer, and also has a write-back function and a write-through function. When recording using a write-back function designated by a recording designation flag, the maximum number of substitutions of defective sectors is automatically set to a given value for a write-back operation, and a mode display indicates that a write-back mode has been selected. The write-back operation is inhibited by a write-back inhibit flag according to the frequency of occurrence of the substitutions or the condition of a substitute area to thereby enhance the reliability of recording information.
