Title: Disc controlling system
Inventor: OGAWA YUUJI
IPC: G11B20/12
Filed: 1981-06-30
Abstract: PURPOSE:To decrease the processing time at cylinder switching, by eliminating the need for the seek time for block change, through the assignment of a change block in the final track at each cylinder. CONSTITUTION:When read/write transfer request for 2-block's share is given from a block 279, a controller gives a seek instruction to a disc device to seek the next cylinder after the end of data transfer of the block 279. After the end of seek, the detection of the final sector of the head number 0 is waited and if detected, the read/write transfer is executed from a block 280. The final block 279 of the previous cylinder is processed. Further, since the change block for a revolving time's share corresponding to the required time for the search of the seek and head block is assigned, the read/write processing for the next block 280 can be executed immediately without waiting one revolution.

Title: Memory device
Inventor: TAKAHASHI KENJI
IPC: G06F3/06
Filed: 1985-05-17
Abstract: PURPOSE:To ensure the smooth continuation of operation of an electronic device such as a computer, etc. by saving a storage data within a memory to a medium recorder when the level of the battery voltage is lowered and then resetting the storage data when the battery is replaced. CONSTITUTION:When the voltage level of a battery 6 is lowered, a CPU 2 confirms the voltage drop by a power supply voltage monitor circuit 1 via a signal line l4 and reads the data out of a memory 3. Then the CPU 2 transfers the read-out data to a disk controller 4 via a signal line l3, a bus line l1 and a signal line l5 and stores it in a disk device 5. Then it is retrieved successively whether or not a sector having a back-up number bit BUNB against the device 5 exists after the replacement of the battery 6. If such sectors are detected, they are read out of the device 5 in the order of smaller bits BUNB and led to the controller 4. Then these sectors are transferred to the memory 3 from the line l5 via both lines l1 and l3 and arrayed again. Thus a memory pattern can be restored in a voltage drop mode and an electronic device such as a computer, etc. can be operated continuously with no trouble.
