Title: Magnetic storage device
Inventor: SHIBATA MAKOTO
IPC: G11B5/02
Filed: 1980-12-24
Abstract: PURPOSE:To improve the frequency characteristics, by locating a main magnetic pole and an auxiliary magnetic pole to clip a disc magnetized toward vertical direction to a plate surface from the front and back and making thinner the thickness of the main magnetic pole corresponding to a circumference track. CONSTITUTION:The thickness of the main magnetic pole for vertical magnetic recording consisting of the main and auxiliary magnetic poles is changed from the inner and outer circumferences. For example, when 1.5mum at the outermost circumference radius 10cm and 1.1mum at the innermost circumference radius 7cm are taken, the output response by frequencies is as shown in figure. The change in signal amplitude by the frequencies is the same for any track, and the effect of lower point produced without fail can be avoided. The curve 41 is the output response for the innermost circumference and the curve 42 is that for the outermost circumference. Although the output level is lowered as a whole, the decrease can be compensated by the control of the gain of the amplifier system. The head width at the intermediate region other than the outer and inner circumference can be set stepwise in accordance with the distance from the center or continuously. For example, the main magnetic poles 52 are 12 poles in total and they are supported with a holder 51. Thus, recording with high density can be made.

Filed: 1981-11-17
Abstract: PURPOSE:To decide a position of the own node in a collision node train by a simple circuit, by detecting a position of other nodes, from a direction of a signal from other node, received by each node which has collided. CONSTITUTION:When an optical receiver is connected to each of signal receiving waveguides 5-1, 5-2, a direction of a receiving signal can be discriminated. When plural nodes execute transmission to a transmission line 1 almost simultaneously, in case when a node which causes a collision of a signal is generated in these plural nodes, it can be decided that the node which has caused a collision exists,  by receiving some signal in the course of transmission. In this case, it can be decided that a node which has received a signal from the right side only is positioned at the left end of a collision node row, and a node which has received it from the left side only is positioned at the right end. Also, it can be deicded that a node which has received it from both sides is positioned between at least 2 collision nodes. In this regard, in this coupling device, 6-1 and 6-2 denote signal transmitting waveguides used in the right direction and the left direction, respectively.
