摘要： The present invention is a servo signal recording method for recording a servo signal on a magnetic tape having a data band and a servo band, wherein erasure is performed based on a pulse having a duty ratio varied so that a driving time of the AC erasing head with respect to one polarity is longer than a driving time thereof with respect to the other polarity, and then, the servo band is magnetized so as to have a magnetization direction opposite to magnetization direction caused by the erasure to record a servo signal in the servo band. According to this configuration, the influence of an information recording signal recorded on the surface of a magnetic recording medium on a reproduction output is reduced, whereby the reproduction output of a servo signal can be enhanced easily.

摘要： Method and apparatus for punching the tuyeres of a converter with a mechanical puncher mounted upon a carriage running on rails. Light intercepting plates encoded by light transmission holes are disposed opposite each tuyere. Light is shone towards the light intercepting plates and detected on the opposite side thereof by photoelectric elements the outputs of which are coupled to a digital processor which controls the speed and position of the carriage. The mechanical puncher has two cylinders each of which drives two punching rods to successively punch the tuyeres. If it is impossible to punch a tuyere with the mechanical puncher were moving in one direction, the position of the puncher is shifted by one tuyere to start the punching again in the opposite direction.

摘要： A data recording apparatus of the present invention includes a head that records data signals by magnetizing a magnetic tape 10 and a recording control portion that controls the recording operation by causing recording current to flow to the head. The recording control portion controls the operation of the head, so that in the magnetic tape 10, which is direct current demagnetized continuously in the longitudinal direction, a magnetic field is formed intermittently in an opposite direction to the magnetization direction of the direct current demagnetization. Thus, when recording data signals on the magnetic recording medium, it is possible to make the current flowing to the head small and to realize apparatus power consumption reductions, load reductions for the head and circuitry, and reduction in crosstalk noise from the head chip used for writing to the head chip used for reading.

摘要： A magnetic tape driving apparatus, which does not cause damage to either a magnetic head or a magnetic tape when making transition of the magnetic tape from a stopped state to a running state, when making transition of the magnetic tape from a running state to a stopped state, or when reversing the transportation direction of the magnetic tape, is provided. In a state where any one of a magnetic head and a magnetic tape moves and the other rests (i.e., a state where static friction may occur), such as at the time of starting transportation of the magnetic tape, at the time of stopping the tape in a running state, and at the time of reversing the transportation direction of the magnetic tape, a head displacing portion vibrates the magnetic head under the control by a displacement control portion, and thus no static friction occurs between the magnetic head and the magnetic tape. Therefore, the risk of causing damage to the magnetic head (such as an MR head unit equipped with an MR element) or the magnetic tape can be reduced.

摘要： In the apparatus and method of the invention, a servo signal reproduction unit generates a PES from a servo signal reproduced from a magnetic tape, and a frequency conversion unit performs FFT processing of the PES to generate frequency component information. Then, a filter value generation unit generates filter values based on the frequency component information and writes these to a memory. When recording various data signals to the magnetic tape, the filter values are read from the memory and a control filter serving as a notch filter is incorporated into a feedback control for a tracking servo. This enables periodic and narrow-band noise to be removed from a PES, consequently reducing PESs. Accordingly, learning-type optimum notch filter control that allows a magnetic head to follow recording tracks at high speed and with high precision is possible even when the recording track width is reduced and the tape speed is increased.
