Title: Rotary head type information recording and reproducing device
Inventor: SAKURAI KEIICHI
IPC: G11B5/09
Filed: 1989-09-20
Abstract: PURPOSE:To reduce the cost by preparing a circuit generating a timing signal corresponding to 1st and 2nd cylinders with respective diameters and selecting any timing signal corresponding to the diameter of the loaded cylinder. CONSTITUTION:A reference clock from any of frequency dividers 6, 8, 9 are selected by a selectors 10a - 10c and inputted to an address counter 11. The address counter 11 counts the reference clock, frequency-divides the frequency to generate a clock corresponding to the block and outputs the result to a timing ROM 12. In this case, the timing ROM 12 generates various timing signals REC, Area, ATFW, PCM or the like from the inputted block clock. Selectors 13a - 13c select any of signals generated from the timing ROM 12 in response to the diameter of a cylinder 1. Thus, common components to different devices are used and the cost is reduced.

Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To suppress a charge/discharge current caused by coupling capacity between electrodes when an active element is driven and to make it high picture quality, low power consumption by arranging at least one among a signal line, a gate line and the active element on a substrate surface of a side opposite to the side provided with a capacitive load. SOLUTION: At least one from among the signal line 4, the gate line 9 and the active element 5 is arranged on an array substrate surface of the side opposite to the side facing on a display medium layer.

Abstract: PURPOSE:To provide a magnetic tape which exhibits excellent traveling stability, averts the degradation in electromagnetic conversion characteristics and has good wear resistance on the rear face of a base by providing projection groups to the rear face side of a base film and incorporating liquid or semi-solid lubricating agent into a magnetic layer. CONSTITUTION:This recording medium is constituted by providing projection groups, in which >=70% of the entire part is in a 2-30mum range of the base part diameter, on at least the rear face side of the base film and incorporating the liquid or semi-solid lubricating agent into the magnetic layer at >=0.3mg per 1m<2> surface area of the magnetic layer. Namely, the surface has the rough surface state having the projection groups and, therefore, the contact area with an object with which said surfaces comes into contact is small and the friction is lowered. The contact resistance during tape traveling is low and good slipperiness is exhibited. The surface characteristics such as roughness, rugged shapes, hardness, density, and surface energy of the surface of the magnetic layer are made into the characteristics which hardly induce meandering in combination with the surface characteristic of the rear face of the tape if the liquid or semi-solid lubricating agent is incorporated into the magnetic layer at >=0.3mg per 1m<2> of the surface area of the magnetic layer. The excellent traveling stability is thereby exhibited and the good wear resistance of the rear face of the tape is obtd. The good electromagnetic conversion characteristics are thus exhibited.
