摘要： PURPOSE:To obtain such information that the period when an alarm may arise is preliminarily outputted as a periodical maintenance time to easily build the maintenance plan of an optical disk in the maintenance operation of the whole of a system. CONSTITUTION:A dust detector 1 detects the quantity of peripheral dust and outputs it to an A/D converter 2 by a voltage output. The quantity of dust converted to digital data by the A/D converter 2 is calculated and outputted as the actual cleaning time of an optical head or the like by a microprocessor 3 and a function table 4 which is prepared as a data table by preliminarily examining relations between the quantity of dust and the abnormality recovery processing rate like the alternative sector use rate in recording to the optical disk or the data correction rate in reproducing. Outputted information is sent to a display part 6 through an output interface 5 to a display part 6 and is sent to the display part 6. Information of the time when the optical head or the like should be cleaned is displayed on the display part 6.

摘要： PROBLEM TO BE SOLVED: To provide a method and system where a TV receiver side discriminates the attribute of a viewer and reflects the attribute on a TV output signal so as to provide a broadcast signal to the viewer suitably thereto and a program production side can produce programs and transmit signals without caring about viewers. SOLUTION: A viewer inserts a viewer card to enter attention attribute of the viewer to a TV receiver outputting video and audio before viewing a TV program, and the TV receiver generates an attention attribute table of the viewer. The TV receiver analyzes an input signal received therein according to a program corresponding to the attribute when the viewer views a broadcast program and applies conversion to the signal from the standpoint of the attribute so as to allow the viewer to easily view the broadcast program. The TV receiver outputs a converted TV output signal so as to provide the view environment customized to each viewer to the viewer.

摘要： PROBLEM TO BE SOLVED: To prevent an erroneous writing at the abnormality of sector pulse by performing time monitoring from a servo data till an object sector at the time of write-in to a recording medium in a magnetic disk device using an ID-less format. SOLUTION: In a write-in to a recording medium 7, a microcontroller 3 instructs the number of sectors from the servo data till the object sector to a formator control 2. A window pulse generating counter 8 generates a window pulse at a timing when the sector pule of the object sector is to be detected. A sector pulse monitoring part 1 releases the mask of a write gate only in the case it detects the sector pulse when the window pulse is '1', to permit the write-in to the recording medium. The part 1 blocks the write-in to the medium in the case it detects the sector pulse when the window pulse is '0'.

摘要： PROBLEM TO BE SOLVED: To attain the decrease of frequency disabling write cache performance because of buffer empty wait and the improvement of performance through a method for temporarily and sequentially writing write data into a saving area provided on a disk corresponding to write commands continuously issued by random access. SOLUTION: The continuous write to positions 21, 22 and 23 on a recording medium is temporarily and sequentially performed into the saving area shown by 20. When there is no host access, the data written in the saving area are returned to the positions 21, 22 and 23. Since the write end of write data to the saving area corresponding to the write command continuously issued by the random access becomes the end of write to the host requested position, seeking from the position 21 to 22 and from 22 to 23 on the disk is not required and a buffer can be made empty speedily just for that time.

摘要： PROBLEM TO BE SOLVED: To permit the access to a recording region exceeding a BIOS limit value by identifying a master command and a slave command, executing recording and reproducing operations to the regions of a recording medium previously allocated to the respective commands and having magnetic disk devices identified in such a manner that the master and slave disk devices exist in one magnetic disk device. SOLUTION: A disk controller 7 receives the command issued from a host computer 1 and makes discrimination as to whether the target drive of the command from a drive selection register is the master side or the slave side. If the command is issued to the master side, its desired address is held and if the command is issued for the slave side, the address obtained by adding an offset value for an already determined value component to the desired address is determined as the desired address and the access is made to the recording region of the recording medium 10. The access beyond the BIOS limit value is made possible by dividing the recording region of the recording medium 10 into the recording regions 11 and 12.

摘要： PROBLEM TO BE SOLVED: To shorten the overhead time required for executing the straddling of a track by starting a repositioning operation to an adjacent track without waiting a normal completion judgement by a read/write data control part at the time of completing a track access prior to executing the straddling of a straddling track.
SOLUTION: A positioning control part makes access to end data sector 3 being in a target physical track N by an access request by performing a head positioning operation while using servo data 1. At this access completion time, the part starts a repositioning operation to an adjacent physical track N+1 without waiting the normal completion judgement by the read/write control part. Then, the parts performs a positioning operation to the leading data sector 6 in the physical track N+1 being a sector position continuous to the pre- accessed data sector 3. Thus, at the time of executing an access straddling the physical track, the repositioning start to a next target track can be performed in the shortest time by using the servo data.
