Updating optical disk storage
2 is a block diagram showing a data compression/decompression module interposed between the host interface and the RAM buffer memory of FIG. In other words, communication between the optical disk and the computer 19 is "plug compatible" with the conventional communication between the computer 19 and a conventional tape drive.
In this way, no modification of the host's operating system or software is required.
Another embodiment of the invention includes a method for storing compressed data on the systems described above where the following steps are performed in response to a request from a host computer to store a sequence of records: the sequence of records is received at the host interface means and is transferred to the data compression means; the sequence of records is compressed by the data compression means; the sequence of compressed records is transferred to the buffer memory means; the sequence of compressed records is stored in the buffer memory means; a record directory is created in the buffer memory means; the record directory is associated with up to a predetermined number of the compressed records; and the sequence of compressed records and the record directory are stored on the optical media storage device. As explained in that patent, computer 19 represents any computer, e.g., a Digital Equipment Company VAX 11/780, which provides an output for recording on various conventional peripheral data storage devices.
In response to a request from the host computer for the supply of one or more of the stored, compressed records, the present method can further include the steps of: copying all of the compressed records associated with the record directory with which the particular record or records sought by the host are associated into the buffer memory means; employing the record directory to locate the particular compressed record or records sought by the host; transferring the compressed record or records sought to the data compression means; decompressing the records or record sought in the data compression means; transferring the decompressed records from the data compression means to the host interface means; and transferring the record or records sought to the host from the host interface means. Such devices include magnetic tape drives, e.g., a nine-track drive, whereby data is recorded on nine tracks of a tape.
b2b_bbs_msg_id=308I found that, and it appears to address my issue...it doesn't say how to update the firmware. Booting the system to DOS mode by bootable media.(which with this F/W flash program)."How the crap do I do that??
An improved optical disk data storage system method are disclosed. This system also includes optical media storage means for storing compressed data thereon, for storing compressed data received from the buffer memory means, and for supplying compressed data stored thereon to the buffer memory means, and microprocessor means for responding to the sequence of commands received from the host interface means and for controlling data storage and retrieval operations of the buffer memory means and the optical media storage means responsive to the sequence of commands.
It is the slowest element of that system, and is the primary source of delay in storing and retrieving data.
The greater the amount of data, the greater will be the amount of time required for the optical disk to complete its storage and retrieval tasks.
The controller, which includes a microprocessor, (1) receives data transmitted from the host computer, (2) generates information for a high-level directory, (3) constructs embedded directory entries, (4) controls writing of the record data, and (5) writes a high-level directory entry, including a table of embedded directory disk addresses, onto the optical disk.
The above steps are accomplished by an optical disk controller unit interposed between a host computer and an optical disk storage system.
