摘要： PROBLEM TO BE SOLVED: To provide a data format by which a preamble can be reproduced properly and data can be reproduced properly, even if the phases of recording signals of respective tracks do not match. SOLUTION: In the data format in which a unit being one unit of signal processing for reproducing data is constituted of a plurality of tracks, the preamble, such as, gain control pattern and synchronizing which are added to data to control reproduction of data is arranged so that the positions in the direction of progress of a track does not overlap the preamble of the other track in the same unit. Since the preambles of the adjacent plurality of tracks will not be reproduced simultaneously by a reproducing head, even when the phases of the recording signals of respective tracks are not adjusted, since the reproduced signals of the preambles of adjacent tracks will not cancel each other, reproduction of data can be performed properly.

摘要翻译：要解决的问题：即使相应磁道的记录信号的相位不匹配，提供可以正确地再现前同步码并且可以适当地再现数据的数据格式。解决方案：在其中作为一个单位的用于再现数据的信号处理的单元由多个轨道构成的数据格式中，前导码例如增益控制模式和同步被添加到数据以控制再现数据的再现数据被布置成使得轨道的进展方向上的位置不与相同单元中的另一轨道的前导码重叠。由于相邻多个磁道的前导码不会被再现头同时再现，所以即使当各个磁道的记录信号的相位未被调整时，由于相邻磁道的前同步码的重放信号不会相互抵消，可以适当地执行数据的再现。版权所有（C）2009，JPO＆INPIT

摘要： PURPOSE: To obtain a high reproducing output by setting a magneto resistance element head against a rotary drum with a head protruding amount so as to form a space between the head tip of the magneto resistance element head and a tape magnetic surface. CONSTITUTION: A magneto resistance element head 8 is provided with a head chip 19 and a head base 18. The head chip 19 is stuck and fixed to the head base 18 with an adhesive. This head base 18 is fixed with a screw 7b during rotation. An air film AF as a space is actively formed between the head tip 19a of the head chip 19 and the magnetic surface of a magnetic tape T. In other words, the head tip 19a of the head chip 19 is set in a position drawn back slightly more than the outer peripheral surface 73 of a rotating drum 7. Thus, the head is set against the drum with a head protruding amount so as to form a space between the head tip 19a and the tape magnetic surface.

摘要： PROBLEM TO BE SOLVED: To provide a recording and reproducing device in which gain adjustment for an output of a reproducing head is properly performed without requiring a phase adjustment process, and good reproduction of data can be performed.
SOLUTION: One wide width recording head W0 and recording heads W1, W2, W3 of M pieces are mounted on a recording head array 150. Head width of the wide width recording head W0 is same as width of signals of M pieces recorded simultaneously in a magnetic recording medium 2 by recording heads W1, W2, W3 of M pieces which record a plurality of tracks being one unit of signal processing for reproducing data, or more. Deterioration by phase deviation of a signal for AGC is never caused during reproduction by recording simultaneously signals for AGC in which phases are adjusted in a plurality of tracks by the wide width recording head W0. Thereby, gain adjustment for an output of the reproducing head can be performed good.

摘要： PROBLEM TO BE SOLVED: To optimize regenerative signals outputted from a reproducing head by a method wherein a bias current given to the reproducing head of a magnetoresistance element of a rotary drum is controlled in intensity corresponding to the degree of abrasion of the reproducing head. SOLUTION: A bias current control means 200 has a function to control a bias current value BCD given to a reproducing head RH so as to make the output RST of regenerative signals RS of a reproducing amplifier 43 connected to the reproducing head RH of a magnetoresistance element. Therefore, when a bias current is varied by abrasion of the head, the output RST of regenerative signals RS obtained through reproducing amplifiers 43 and 43c is changed. A gain control 41a controls the since wave gain of an oscillator 41 corresponding to a change in the output RST of the regenerative signals RS, and a control signal CSS is sent to a bias current circuit 201 at a point P1 , whereby the voltage BCU of the reproducing head RH can be set variable so as to make the output RST of the regenerative signals RS optimal.
