摘要： PROBLEM TO BE SOLVED: To prevent the dielectric breakdown of an MR head and a GMR head. SOLUTION: This magnetic head device is constructed in such a manner that a magnetoresistive effect magnetic head is mounted on a head base, and the lead electrode of this magnetoresistive effect magnetic head is connected to an electrode pattern formed on the head base. In an unused state, land parts as the external terminals of the electrode pattern are short-circuited from each other. In a used state, the short-circuiting is released. While the land parts of the electrode pattern, to which the lead electrode of the magnetoresistive effect magnetic head is connected, are in the short-circuited state from each other, electric charges are accumulated in the magnetoresistive effect magnetic head, and thus dielectric breakdown is prevented. Also, by releasing the short- circuiting in use, any interferences with the operation of the magnetoresistive effect magnetic head are prevented.

摘要： PURPOSE:To record and reproduce information with a large optical head even when a disk cartridge is miniaturized by providing a connecting means on overlapped parts of more than one slide member and moving them under the overlapping state into a position of opening an aperture part for recording and reproducing an information signal. CONSTITUTION:The disk cartridge is equipped with a cartridge main body 1 and a shutter 6 consisting of a 1st slide member 4 and a 2nd slide member 5 to be freely movably fitted to this main body 1. The slide members 4 and 5 are equipped with the connecting means on their overlapped parts, and are moved under the overlapping state into the position of opening the aperture part 10 for recording and reproducing the information signal. Consequently, an enough aperture width of the aperture part 10 can be secured, and hence even when the disk cartridge is miniaturized, the information signal can be recorded and reproduced on the information recording medium by using such a large optical head or magnetic head as provided in the conventional information recording and reproducing device.

摘要： PURPOSE:To correctly detect the displacement of a liquid crystal light bulb by providing a light transmission section and a light cutoff section on the liquid crystal light bulb. CONSTITUTION:The laser beam from a laser light source 1 is continuously outputted by a polarizing piece for each dot, and it is swept by a scanning optical system 2 for dots of a liquid crystal light bulb 3. When the swept laser beam is radiated to a light transmission section, the laser beam is fed to an optical fiber cable 62 arranged oppositely to the transmission section, and it is converted into an electric signal by a measuring device 5 and applied to a threshold value detecting circuit 55. The circuit 55 interrupts an arithmetic circuit 57 at the preset threshold value level. The circuit 57 records the scanning state of the optical system 2, i.e., the radiation position of the laser beam on the face of the bulb 3. The actual radiation position when the circuit 55 interrupts is known, and it is compared with the primarily rightful radiation position stored in advance. Correct displacement can be detected without affecting the normal projection.

摘要： PURPOSE:To use the same magnetic transfer device for both the beta system and VHS system in common by providing a reproducing head and a recording head for a control signal on the traveling part of a slave tape after magnetic transfer and specifying the fitting interval between those heads. CONSTITUTION:The control signal CTL transferred magnetically to the slave tape 4 is reproduced by the reproducing head 11, passed through a reproducing amplifier 13, and waveform-shaped by a waveform shaping circuit 14. The waveform-shaped control signal CTL is supplied to a recording head 12 through a recording amplifier 15 and recorded on the slave tape 4 in a saturation state. The fitting interval H between the reproducing head 11 and recording head 12 is set as shown by an equation. In the equation Tbeta is the CTL pitch of the beta system and TVHS is the CTL pitch of the VHS system. Consequently, control signals recording in iota2 recording formats of the NTSC system which differ in the tape speed are recorded at corresponding CTL pitch by using the common magnetic transfer device 10.

摘要： PURPOSE:To prevent the generation of a dislocation of a relative position rela tion between a mother tape and a copy tape by providing an air reserving groove communicating to an air blow-out port on a tape running direction side from the air blow-out port of the wall surface opposed to a tape running surface of an air guide. CONSTITUTION:A strong pressure by air works on tapes 4-6 extending over a wide area from a transfer part T to a detaching part U. That is to way, the pressure in the transfer part T becomes maximum, and the pressure drops in the tape running direction side or the opposite tape running direction side from said part, but since an air reserving groove 22 is provided, a drop rate of its pressure in the area corresponding to its air reserving groove 22 is extremely low. Also, pressure of 90-98% against the maximum value, in other words, pressure which is scarcely changed from the pressure in the transfer part T can be operated on a transferred part positioned between the transfer part T and the detaching part U of the tapes 4-6. In this way, even if a varia tion is generated in a tension of a copy tape 4 and a mother tape 5, a disloca tion of a relative position relation between the tape 4 and 5 is not generated in its transferred part.

摘要： PURPOSE:To prevent damages to a tape with simple construction, by forming an air gap functioning as a air duct at the opposing part of a magnetic head tip generating a transfer bias magnetic field to the tape and pressing each tape on a rotary drum circumference. CONSTITUTION:A magnetic head 8 generating a transfer bias magnetic field is formed by winding a coil 10 around a magnetic core 9, and an air gap 12 communicating a core internal space 11 with the outside is formed at the position of the core 9 opposing to the tape and a rotary drum 3. The air gap 12 is an air gap serving as an air duct without interposing a spacer, and a housing 13 of almost rectangular parallelopiped having an opening at one side is provided to surround the magnetic head 8. The opening of the case 13 is formed in a circular shape so as to be faced to the rotary drum along the drum circumference, and side walls 14, 15 are in close contact with both ends of the core 9 of the magnetic head 8. Further, static pressure chambers 16, 17 surrounded with the housing 13 and the core 9 are formed before and behind the magnetic head 8 along the tape running direction.

摘要： PROBLEM TO BE SOLVED: To obtain a helical scan type magnetic recording/reproducing apparatus having high recording density.
SOLUTION: In the helical scan type magnetic recording/reproducing apparatus in which input data are encoded and recorded by recording heads W1-W4 as signals of n system (e.g. n=4), reproduced by 2n pieces of reproduction heads R1-R8 and subjected to non-tracking process to decode them, each of the recording heads W1-W4 is constituted as one head having four multi-gaps with lower magnetic poles 31 and upper magnetic poles 33 arranged thereon through a gap 32. Core widths CW of the recording heads W2, W3, W4 are each made to be a track pitch TP +α1 and formed to be overlapped with the track pitch TP of the W1-W3 by α1, so that the specified recording width TP can be surely obtained, and the core width CW of the W1 is formed into the track pitch TP +α2 (α2>α1) while taking the fluctuation of the head position one round after into account, then the recording pattern without gap is obtained.
