    • Liquid nitrogen is filled in a low temperature vessel; an ejector that sucks liquid nitrogen by blowing a cooling agent (liquid or gas) such as low temperature helium gas or liquid helium of pressure higher than in the space within the vessel is disposed in the vessel; the liquid nitrogen blown with the cooling agent is cooled by the cooling agent to become fine particles of solid nitrogen which fall down; and gas in a space of the vessel is discharged out of the vessel so as to maintain the pressure of the space higher than the atmospheric pressure. A gaseous phase of liquid nitrogen in an adiabatic vessel is depressurized to vaporize nitrogen in a liquid phase so that the temperature of the nitrogen reaches the triple point of nitrogen by lowering the temperature to thereby produce solid nitrogen by keeping the temperature at the triple point, and that the produced solid nitrogen is transformed into slush by stirring the content of the adiabatic vessel. A super conductive body formed of a material exhibiting a state of super conductance in the vicinity of the temperature of liquid nitrogen or of the temperature where liquid nitrogen and solid nitrogen coexist can be cooled by immersing the body in slush nitrogen held in an adiabatic vessel or flowing in an adiabatic pipe.
    • 液氮填充在低温容器中; 喷射器通过吹送诸如低温氦气或低于容器内的空间的压力的液氦的冷却剂(液体或气体)而吸入液氮; 用冷却剂吹入的液氮被冷却剂冷却,成为脱落的固体氮的细小颗粒; 并且将容器的空间中的气体排出容器,以保持空间的压力高于大气压力。 将绝热容器中的氮气气相减压以使液相中的氮气蒸发,使得氮气的温度通过降低温度而达到氮的三重点,从而通过将温度保持在三重点来产生固体氮, 并且通过搅拌绝热容器的内容物将所产生的固体氮转变成泥浆。 在液氮温度附近或液氮和固态氮共存的温度下表现出超导状态的材料形成的超导体可以通过将本体浸入保持在绝热容器中的冰冷氮气中来冷却,或 在绝热管中流动。

    • A rotary-type magnetic recording medium has servo patterns formed in servo pattern regions on a substrate by patterns including recording regions and non-recording regions. Burst signal units composed of the recording regions or the non-recording regions are formed in burst pattern regions in the servo pattern regions. The burst signal units are formed so that for at least one edge out of both edges along a direction of rotation of the magnetic recording medium, a center in the direction of rotation is positioned closer to the other edge than both ends in the direction of rotation, and a ratio of a length along a radial direction of the magnetic recording medium between both ends and the center of the one edge to a length along the radial direction between both ends of the one edge and both ends of the other edge is in a range of 0.2 or below.
    • 旋转型磁记录介质具有通过包括记录区域和非记录区域的图案在基板上的伺服图案区域中形成的伺服图案。 由记录区域或非记录区域组成的突发信号单元形成在伺服图案区域中的突发模式区域中。 突发信号单元被形成为使得对于沿着磁记录介质的旋转方向的两个边缘中的至少一个边缘,旋转方向上的中心比旋转方向上的两端更靠近另一边缘 并且沿着一端的两端与一边的中心之间的磁记录介质的沿径向的长度与该另一边的两端两端之间沿径向的长度的比率为 范围在0.2以下。

    • An information medium which is capable of maintaining the protection capability by a lubricant for a long term. An information medium has a recording area and a non-recording area disposed on at least one surface of a disk-shaped base plate. The information medium is configured such that a lubricant exists on the one surface of the disk-shaped base plate. The recording area is configured such that a protective film formed of DLC exists above the recording layer. At least a surface-side portion of the non-recording area is formed of a resin material having a higher bonding ratio with respect to the lubricant than that of DLC.
    • 能够长期保持润滑剂的保护能力的信息介质。 信息介质具有设置在盘形基板的至少一个表面上的记录区域和非记录区域。 信息介质构造成使得在盘形基板的一个表面上存在润滑剂。 记录区域被配置为使得由DLC形成的保护膜存在于记录层之上。 非记录区域的至少表面侧部分由与DLC相比具有比润滑剂更高的粘结比的树脂材料形成。
