Title: Power feeding circuit
Inventor: YAMAZAKI AKIRA
IPC: H04M19/00
Filed: 1979-06-11
Abstract: PURPOSE:To enable to use the output voltage of the power feeding unit efficiently, by balancing the positive and negative sides of the applied voltage to the line through varied grounding point. CONSTITUTION:The power feeding circuit 1 is provided with the circuit 6 which can change the grounding point. When the relation of E<+>>¦E<->¦ is caused between the applied voltages E<+>, E<-> to ground to the lines 4 and 5, E<+>=E<-> is obtained by moving the grounded point to the negative side from the neutral point by E<+>-¦E<->¦ with the circuit 6. Accordingly, even if the condition of E3 E4 is taken place for the voltage drops E3, E4 at the relay units 2 and 3, E<+>+¦E<->¦=2ET (where; ET is the ground applied voltage to the permitted line) is possible, resulting in effectively using the power feeding voltage of the power feeding unit.

Title: Magnetic disk
Inventor: SHIMIZU TORU
IPC: G11B5/82
Filed: 1994-03-18
Abstract: PURPOSE:To prevent the occurrence of the unstable floating of a head and head crash, etc., when a magnetic disk is driven by forming an identification symbol with a magnetic signal. CONSTITUTION:In the magnetic disk formed successively out of a substrate layer, a magnetic layer and a protection layer on a substrate and applied with the identification symbol on its non-recording area, the identification symbol is formed by the magnetic signal. Although the area to which the identification symbol is applied may be either side of the inside 2 and the outside 3 of a recording area 1 formed into a disk shape, the inside 2 of the recording area is preferred, and the inside 5 of a CSS zone 4 placed on the innermost side of the inside 2 most preferable. Since the magnetic signal applies the identification symbol within the surface of the magnetic layer, the flatness and run-out (waviness in the circumferential direction) of the magnetic disk are not impaired by the identification symbol. Thus, the magnetic disk generates no ruggedness when the identification symbol is applied, and the disk is prevented from being distorted by thermal stress, and the occurrence of the unstable floating of the head and the head crash, etc., are prevented.
