Title: Optical carrier recording and reproducing device
Inventor: SAKUMA HIROTO
IPC: G11B7/0045
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To obtain a highly operable optical carrier recording and reproducing device by reproducing recorded data and the information indicating that the data are recorded over two or more optical carriers from an optical carrier and, when the data are recorded over two or more optical carriers, inhibiting edition. SOLUTION: Whether or not a mini disk(MD) is connected with another MD is judged by checking the management information of the table-of-content information of the MD for the connecting information of first and second MDs. When the MD is not connected with another MD, a system controller performs an instructed editing process. When the MD is connected to another MD, the controller 15 refuses the instructed editing process and displays that the editing work is impossible on a display 19. Thus the edition is only performed on MDs which are not connected to the table-ofcontent information by refusing the edition on the MDs on which the information connected to the table-of-content information is already recorded. Therefore, erroneous edition can be prevented by detecting whether or not a recorded block to be edited is recorded over a plurality of MDs.

IPC: B23K9/29
Filed: 1981-11-30
Abstract: PURPOSE:To prevent a sputter from entering a feeding part, and to improve operability by covering the tip part of a guide member with a contacting member, and allowing this tip part and contacting member to move relatively. CONSTITUTION:An electrode wire 17 is constrained by a guide member 3 and the tip part of a contacting member 7, i.e. a feeding member 6 while in sliding contact is conveyed to a welding position. A feeding member 6 supported by a supporting member 5 is energized by a pressure applying means 15 to abuts on the electrode wire 17 without reference to its consumption, securing electricity feeding. The tip part of the guide member 3 is covered by being fitted in the bottomed hole 602 of the contacting member 7, so a sputter is hard to enter the conveyance path of the electrode wire 17. Consequently, the conveying properties of the electrode wire 17 and a feeding state are prevented from deteriorating, and even when the contacting member wears off, the same welding as welding in an initial state is carried out.
