Abstract: PURPOSE:To reduce insufficient cooling and supercooling as much as possible by making temperatures of troughs, conductors and telephone-tunnel almost uniform through making cooling pipes of forward and backward routes almost equal in the surface area, thermal resistance and number of pipes. CONSTITUTION:Cooling water 10 is force-fed to a telephone-tunnel 5 via water pipe 6. The cooling water 10 is distributed to forward route cooling pipes 12 by a header 71 to flow through the cooling pipes 12 while cooling the inside of troughs 14. The flows of the cooling water 10 join once by a header 72 and are again distributed to backward route cooling pipes 11 by a header 73. The cooling water 10 is caused to flow through the backward route cooling pipes 11 while cooling air in the telephone- tunnel 5. Then, the cooling water is collected by a header 74 and returned to a heat storage tank 3 via a return pipe 15. The forward and backward route cooling pipes 11, 12 are made almost equal in the surface area. thermal resistance and number of pipes. Therefore, the temperature gradient of the cooling water 10 is made almost equal so that supercooled and insufficiently cooled parts of respective cooling pipes 12, 11 compensate for each other. Thus, the whole of troughs 14, conductors and telephonetunnel 5 is cooled almost uniformly.

Title: Magnetic recording and reproducing device
Inventor: OHINATA YUSUKE
IPC: G11B21/21
Filed: 1994-09-14
Abstract: PURPOSE: To achieve high-density recording by enhancing the resolution of recording and reproducing and also to secure reliability even when using an MR head system and a contact recording system in the magnetic recording device which controls the head load or spacing. CONSTITUTION: The magnetic head 2 detects the relative position between the head 2 and the recording medium 1 using the fundamental wave or higher harmonic signal amplitudes at the time of reproducing the servo signals 20 or the control signals 29 recorded side by side on the recording medium 1. When, for example, the servo signals 29 of the burst pattern are used, tracking is conducted in the manner that the signal amplitude ratios of the burst, A22 and B23, on both sides of the track are equal, and, at the time of on-track, the amplitude of the reproduced signal 12 varies depending on only the relative positions of the head 2 and the medium 1. The signal 12 is inputted into the comparator 9 through the amplifier 7.  The difference signal 15 given by the comparison with the reference amplitude stored on the memory 8 is fed to the drive circuit 11 through the control circuit 10, the output signal 16 of which causes the drive element 5 to be elongated or contracted and to thereby regulate the relative position at a specified amount. When higher harmonic waves are used in the reproduced signal 16, the change depending on the amount of levitation in the amplitude of the reproduced signals is made large and accordingly detection with higher precision is accomplished.
