摘要： PURPOSE:To maintain high accuracy reproducibility of setting of the center of a magnet sheet by providing a flexible magnetic sheet, a holding member for interposing and fixing the peripheral part of mounting hole of the magnetic sheet and a core member formed of ferromagnetic metal having wear-resistance. CONSTITUTION:The core member 55 is formed in a flat disk from magnetic metal having approximately the same thermal expansion coefficient as that of the magnetic sheet and showing wear-resistance. It has a center hole 55a for inserting a rotary shaft. A driving pin inserting hole 55a is provided in the vicinity of the inserting hole 55a for inserting a driving pin for the holder main body 54. A pair of turn stopping notched part 54c are provided in a facing relation to the radial direction at the outer periphery. The insertion hole 55a is punched in the form of a square and shaped, and has a neck part 55d having its periphery extended upwards by burring. In such a manner, high accuracy reproducibility of setting the center of the magnetic sheet is considerably improved so that recording and reproduction of the information can be executed accurately and excellently from the outer periphery towards the inner periphery of the magnetic sheet.

摘要： PURPOSE:To control an accessor so as to be positioned in an accurate position by correcting a place where the accessor is positioned based on plural position pattern detection signals. CONSTITUTION:A resetting part 25 is made up of a position resetting circuit 251 resetting a count circuit 256 with the aid of a detection signal (2) that is transmitted from a cell sensor 35a and detects the start edges of cell patterns CP, and a position resetting circuit 252 resetting the count circuit 26 with the aid of a detection signal (3) when a mid sensor 35b detects the start edge of a mid pattern lying in a place where positioning is recognized among plural mid patterns MP. When a pulse from a tachogenerator 32 subtractes the reading of the count circuit 26 to become zero, an MPU 1 recognizes whether the detection signal (3) of the mid sensor 35 is present or not. If so, the MPU 1 judges that the accessor is positioned normally and shafts to next operations.

摘要： PURPOSE:To prevent crack or damage by providing a projection inscribed with a hole of an opposite frame to a boss being a reference of a storage cell to avoid force delivered to the root of the boss due to temperature changes. CONSTITUTION:The projection 15 circumscribed with a hole 11 of a frame 9 is provided to a boss 10A being a reference of a storage cell 8. Bosses 10B, 10C of other storage cell 8 have a projection 12 horizontally and the boss 10B is formed to be escaped vertically so that the boss 10B is fitted even when the boss pitch of the storage cell 8 and the hole pitch of the opposite frame 9 are deviated and the boss 10C is used simply for mounting. The projection 15 is provided to the boss 10A being the reference of the storage cell 8 in this way to make the positioning accuracy accurate. Further, even when there is a change in size depending on the difference from materials used for the frame 9 and the storage cell 8, only the projection 15 receives force and the entire boss does not receive force. Thus, no crack damage is given to the boss 10A.

摘要： PURPOSE:To make improvements in aseismatic reliability ever so better, by installing two types of large and small picker driving mechanism in terms of driving force, and constituting the driving mechanism so as to be selected to the large driving force on the basis of earthquake occurring detection. CONSTITUTION:When an earthquake occurs while an operating mode indicator 25 indicates a transfer operating mode, an output line of a gap photocell 23b varies from ON to OFF and transmitted to an AND circuit 32. Since an AND circuit 31 is OFF because it is in the transfer operating mode, the AND circuit 32 and an OR circuit 30 both are turned off. On the other hand, a select switch 33 selects a drive circuit of a picker motor 19 from a first drive circuit 34 to a second drive circuit 35. Even at the time of picker excitation by a maximum earthquake to the second drive circuit 35, this picker is drawn in a carriage mechanism, making it take ability to generate driving force whereby a collision or the like of the cell, etc., is preventable. With this constitution, aseismatic reliability is improvable.

摘要： PURPOSE:To enable to increase the precision of pointer through accurate detection of data position in error, by using the information relating to the polarity of reproduction signal or combining it with the information relating to the level. CONSTITUTION:In the digital magnetic recorder such as magnetic tape, when the input signal is of positive or negative polarity, the comparators 9, 10 output the signal waveforms 3, 4 by the width of period corresponded respectively. The output is latched to the flip-flops (FF)11, 13 in synchronizing with the respective clock to set the information of the polarity, and this information is set to FF12, 14 at the next clock and simultaneously FF11, 13 are reset. Thus, when the polarity of waveform is alternately appeared, FF11, 13 and FF12, 14 are alternately set or reset, and when both are all in set state, the error output 22 is picked up from the OR gate 17.

摘要： PURPOSE:To increase the freedom of structure for the control of a storage cell frame concatenation type apparatus by structuring it so as to convert a logical address structured by the code inherent to a frame and addresses in the frame into a physical address by means of a frame information. CONSTITUTION:A logical address of a cell address for a cell 4 in a frame is structured by defining it with a frame code X inherent to each frame and an in-frame address DELTAX. The control program of a computer issues a from address/to address. A data recorder 6 and tape entry stations 5A and 5B are also afforded with cell addresses. An accessor drive circuit 8, in response to the from address/to address, converts a logical address into a physical address referring to a frame structure information stored in advance and controls carrier systems 1A and 1B. This structure can remove the restrictions on the freedom of structure.
