摘要： In a CD-ROM disk reproducing device, for a data read instruction which specifies an address issued frequently from a host computer, irrespective of whether the device has a Lock Cache function, the time required from receipt of a data read instruction up to the actual data transfer is reduced. The data read instruction which specifies an address issued frequently from the host computer is discriminated by a microcomputer constituting a control section in the device and the read data from the address is locked in a storage section (buffer RAM) so as not to be erased. When a data read instruction specifying the same address is received afterward, data is read out directly from the storage section and transferred to the host computer.
