Title: Method and apparatus for recording and read of variable-speed data by using rotating drum device
Inventor: TSUONNSHIEAU UU
IPC: G11B5/027
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To effectively record and reproduce by maintaining the rotating speed of a rotary drum constant by decelerating the feeding speed of a magnetic medium from a standard speed in response to the information transmission speed of recording information when the information is different by a predetermined amount or more from the standard speed. SOLUTION: The information to be recorded on a magnetic medium 12 is given to an information speed controller 14 and an information speed detecting selector 16, which detects the information transmission speed of an information source, and outputs a transmission speed selection signal. This signal is given to the controller 14, a variable tape speed controller 18 for controlling the feeding speed of the medium 12, and a head switch 20 for controlling the head function. The controller 14 outputs information source information by speed N to a digital signal processor DPS 22. The DPS 22 sends the processed information to a recording amplifier 24. The amplifier 24 sends the information to be recorded to the magnetic head on a drum 11.  In this case, when the recording information is different from the standard speed N by a predetermined amount or more, the magnetic medium feeding speed is decelerated from the speed N in response to the information transmission speed of the recording information.

Title: Automatic preset device
Inventor: NUGA TADAO
IPC: H03J7/18
Filed: 1992-08-27
Abstract: PURPOSE:To attain the operation of automatic preset without disturbing reception of a broadcast by allowing a 2nd tuner section to receive a program for a preset memory while a 1st tuner section receives a program of a broadcast station. CONSTITUTION:A system controller 19 fetches list information from an area of a 1st memory 20 and a 2nd memory 21 respectively. Only frequency data of a broadcast station corresponding to each list information are stored while being rewritten in the order of higher reception electric field strength or of high reception quality by automatic scanning. Furthermore, FM tuner sections A, B are controlled by the controller 19. Moreover, while the tuner section A is in the normal reception operation, the tuner section B implements the reception for seeking a broadcast station. Since the program for a preset memory corresponding only to list information stored in advance is received, the time for receiving the electric field strength and the reception quality over the entire broadcast frequencies is reduced.
