Abstract

PURPOSE:To obtain a memory device of high performance and low cost by executing the recording and readout of index information of an external index memory by an exclusive head provided in a recorder of a video tape, etc., in a tape recording and reproducing device. CONSTITUTION:A magnetic material adhering adhesive tape (hereinafter abbreviated as IM) 5 which has applied a magnetic material to one surface used as an index memory and has applied a pressure sensitive adhesive to the other surface is stuck to the side face of a cassette tape 1. The cassette tape 1 is slid and installed in the direction as indicated with an arrow 8, and when it is sliding, the IM5 contacts a fixed head 6 and slides, therefore, recording and readout of the IM5 are executed. As for the information contents of the IM5, those which are like a table of contents of the tape contents, an absolute address of the tape, etc. are given. Also, a system for recording one picture by compressing the information can also be realized.

Show about. A conventional method for adding an index function to V Tl (as shown in FIG. 1, for example) sets a period 2 in which certain index information is recorded in the recordable portion at the beginning of the cassette tape 1. 7,
A device is being considered that can be recorded and read in the same way as normal signals. The number 4 indicates the third period rA of the image communication following the index information recording period 1. With this method, each time a cassette tape is loaded into the V'I''R, it is necessary to rewind it at the beginning of the tape in order to read the index information, and each time the cassette tape is removed, it is rewound to the beginning of the tape and the index information is read. must be recorded.For this reason, Kana 5!
