Patent Searching and Data


Title:
MAGNETIC RECORDING AND REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JPH06150633
Kind Code:
A
Abstract:

PURPOSE: To search at a high speed by recording a second time code (hour and minute) in a header area of a sub-code which can be read at the time of variable-speed reproduction.

CONSTITUTION: At the time of the start of search, a system controller 1 controls a motor control circuit 5 and drives a fast toward device driving a magnetic tape at a high speed. Also, during fast fowarding, the controller 1 reads the second time code recorded in the header area of the sub-code through a decoder 12b. Then, when a present position is smaller than a speed-change position, the search is executed at a high speed in accordance with the second time code (hour and minute) recorded in the header area of the sub-code. At the time of attaining to the speed-change position by high speed search, the controller 1 reduces a speed to read a first time code (hour, minute and second frame) recorded in the data area of the sub-code. Then, when the present position attains to an objective position, the controller 1 controls the circuit 5 and stops the magnetic tape 9.
