Title: Rotary magnetic head device
Inventor: TERADA AKIMICHI
IPC: G11B5/53
Filed: 1989-11-15
Abstract: PURPOSE:To reduce impact jitter by improving the symmetricity of head arrangement to cancel impact jitter caused at recording and impact jitter caused at reproduction. CONSTITUTION:Dummy heads 30,31,32,33 whose tip shape and projection are nearly equal to those of other heads are arranged just in the middle between recording exclusive heads 7,8 or 9,10 and between reproduction exclusive heads 3,4 or 5,6 and just in the middle between a high fidelity head 11 or 12 and the reproduction exclusive heads 3,4 or 5,6. Then the heads are arranged at an equal angular interval of 30 deg. in the circumferential direction as a whole. When the dummy heads are used in this way, the selecting range of each head interval is widened and the impact jitter at recording and reproduction is entirely cancelled. Thus, a high picture quality picture with less video jitter is obtained by using other heads than the recording heads for the reproduction.

Title: Semiconductor memory
Inventor: MATSUO AKINORI
IPC: G11C16/34
Filed: 1988-11-22
Abstract: PURPOSE:To simplify writing operation control accompanied by writing confirmation by setting writing time in an internal circuit and automatically switching to a reading out mode after writing by the input of a prescribed control signal. CONSTITUTION:Nonvolatile storage elements, the threshold voltage of each of which is changed according to electric writing information, are matrix- arranged for a memory array MARY. For a control circuit CONT, an automatic verifying mode is set by a chip enable signal, the inverse of CE, and the stored data of a data latch circuit DL are written in the array MARY. The writing time is set by counting a write pulse by an output counter circuit CCTR, and the CONT is automatically switched to the reading out mode after the writing. Read out data are compared with the data stored in the latch circuit DL in a comparator circuit EOR, and the coincidence/noncoincidence between the data is decided. Thus, the writing operation control accompanied by the writing confirmation can be simplified.
