    • Since disks of the same type are loaded in a disk device using a conventional disk changer scheme, the disk device is not versatile as a peripheral device of a computer. ROM disks and RAM disks are mixed and stored in a magazine, and this magazine is loaded in the disk device. In the disk device, a tray is identified in step (c) by a detector arranged on the tray to check whether the tray be a ROM disk or a RAM disk. Thereafter, discrimination information is recorded, together with the contents information, on an IC memory Ml arranged on the magazine in step (k), or the discrimination information are recorded, together with the identification code of the magazine, on a memory 5 in step (p). Thereafter, when the magazine is loaded again, the discrimination information is read from the IC memory M1 or the memory 5, and an operation corresponding to each disk is performed.
    • 由于使用常规的磁盘更换器方案将相同类型的磁盘加载到磁盘设备中,所以磁盘设备作为计算机的外围设备不是通用的。 ROM磁盘和RAM磁盘混合并存储在存储盒中,并且该磁带盒装载在磁盘设备中。 在盘装置中,通过布置在托盘上的检测器在步骤(c)中识别托盘,以检查托盘是ROM盘还是RAM盘。 此后,在步骤(k)中将识别信息连同内容信息一起记录在布置在盒子上的IC存储器M1上,或者将识别信息连同杂志的识别码一起记录在存储器5上,步骤 (p)。 此后,当再次加载杂志时,从IC存储器M1或存储器5读取识别信息,并且执行与每个盘相对应的操作。
