Abstract: PROBLEM TO BE SOLVED: To improve easiness to use and convenience of an AV system and the like structured by connecting mutually by an IEEE1394. SOLUTION: As operation of STR side, when other equipment existing on an IEEE1394 bus is selected, PING control command being selection notice information is transmitted in accordance with performing operation of a display key. In an equipment side receiving this PING control command, display indicating that self-equipment is selected for a self-display section is performed. That is, in an equipment side selected by the STR, display of being selected is performed so as to indicate that a self-equipment is selected. By this constitution, for example, display variation as display being selected is obtained in the display section of an equipment being selected responding to operation of a display key. It can be confirmed easily and visually that the equipment is an equipment being selected by watching this condition by a user.

Abstract: PROBLEM TO BE SOLVED: To allow coordinate informatxon on housing parts housing recording media to be stored with a small memory amount. SOLUTION: This device has housing parts housing cassettes and also conveys the cassettes by a cassette conveying machine 16 to the housing parts while forming a cassette library 1 by connecting respective consoles 1B to 1D having recording and reproducing means performing recordings and reproductions to recording media. A library controllor 2 obtains and also stores correction values based on dimensional errors among respective consoles 1B to 1D and among the respective consoles 1B to 1D and the cassette conveying machine 16 by controlling the recording and reproducing means and the machine 16 and also by moving the machine 16 for searches and also obtains and stores coordinates of typical angular windows of the respective consoles 1B to 1D based on these correction values and then it calculates coordinates of the housing parts from these correction values and the coordinates of the typical angular windows.

Abstract: PROBLEM TO BE SOLVED: To restrict generation of troubles when an optical disk records and rotate the optical disk at high speed by detecting a rotation speed of a recording medium and irradiating the recording medium with a light of a determined optimum read power. SOLUTION: A microcomputer 20 for control reads out an amplification factor for RF signals, an amplification factor for FE signals and an offset value of the FE signals from a memory 21 and sets the values to an RF process part 17. The RF process part 17 generates RF signals and FE signals on the basis of the set amplification factors. The microcomputer 20 controls a laser control part 16 to project a laser light of a read power (P1) at a rotation speed time from an optical pickup 11 to the signal face of an optical disk 3, and sets the amplification factor. Then, a laser light higher than the read power (P1) is emitted to the optical disk 3 to set the amplification factor of the RF process part. Correct reproduction with the read power at a high double speed is carried out accordingly.

Abstract: PROBLEM TO BE SOLVED: To obtain optimum light power using smaller number of OPC processings. SOLUTION: In an optical recording and reproducing device, a laser diode 12 emits light beams to a CD-R3 to record or reproduce data. A detector 13 receives the reflected light beams from the CD-R3. An RF processing section 17 extracts ATIP included in reproduced signals. A control microcomputer 20 reads a manufacturer's name and the manufacturer's code of the CD-R from the information recorded in the ATIP as special information, reads the light power corresponding to the CD-R from a memory 21 and determines the power as the initial value of the OPC processings.

Abstract: PROBLEM TO BE SOLVED: To reduce the capacity of power supply (cost) by reducing the instantaneous peak current of a motor for transportation, in a cassette library furnished with a junction port part having upper and lower junction ports for transporting the cassette between the 1st transfer position of a console column L1 and the 2nd transfer position of a console column L2. SOLUTION: The device is provided with a delay part 171, to which the movement control command to the junction port part 18 is inputted, for outputting the movement control command inputted at the non-starting time as it is and also for outputting the movement control command inputted during the starting operation after a lapse of the prescribed delay set time, and a delay time set part 172 for setting the above delay set time to the delay part 171 for starting. By s movement control means 170 such as these parts, the movement control starting time of either one of the upper and lower junction parts is arranged so as to shift with respect to another one.

Abstract: PROBLEM TO BE SOLVED: To perform cassette movement control based on always correct positional information by eliminating the pulse position shifting of the output of a counting means. SOLUTION: A cassette library 1 is provided with a junction console 1J having a junction port for moving a recording medium such as a cassette between the first transfer position of a console column L1 and the second transfer position of a console column L2, a counting means 160 for counting a value proportional to the moving distance of the cassette, a position detecting section 162 for detecting the arrival of the cassette at one of the first and second transfer position, and an initialization control means 161 for initializing the counting means 160 when the arrival is detected by the detecting section 162. The counting means 160 is initialized for each arrival of the cassette at a reference position by the initialization control means 161. Thus, pulse position shifting is prevented from affecting a next carrying operation.

Abstract: PROBLEM TO BE SOLVED: To perform a carrying operation in a small device area without causing any interference between the carriers of a transfer section and a junction port section, and to simplify the control of the two carriers. SOLUTION: A cassette library 1 is provided with a junction port section for moving a cassette between the first transfer position of a console column L1 and the second transfer position of a console column L2 (transfer section), and a shared carrying space connected to the independent carrying space of the transfer section is provided in the carrying space of the junction port section. When the carrier of the junction port section is driven, determination is made by a determining section 161 as to the presence of the carrier (second carrying section) of the transfer section in the shared carrying space, and when the presence of the carrier is confirmed, the carrier is placed on standby in an independent carrying space by a movement control unit 162.
