Title: Magnetic recording and reproducing device
Inventor: HIRONAKA MINORU
IPC: G11B15/02
Filed: 1988-12-27
Abstract: PURPOSE:To keep secrecy in the case of reproducing by recording a password on a magnetic tape. CONSTITUTION:The password(PW) inputted with a key 7 is transmitted to a comparison means 5 by an input judgement means 6. The means 5 compares a reproduced character 14 from a reproducing system 3 with an input character 13. When the character 14 coincides with the character 13, a permission signal 12 is transmitted to a video recording and reproducing circuit 1 and reproducing can be possible. When they do not coincide, reproducing is not performed because of waiting for the input of the PW. When the means 5 judges that nothing is recorded in a PW track 9, the device is in an input waiting state in order to input whether the PW is recorded. Then, Y is inputted by the key 7 in the case of recording the PW, and N is inputted in the case of not recording it and the information is transmitted to the means 5 through the means 6. When Y is inputted, the character 13 is transmitted to a recording system 2 by a generation means 4 and recorded on the PW track 9 through a PW recording and reproducing head 11 and the signal 12 is transmitted to the circuit 1. When N is inputted, the signal 12 has only to be transmitted to the circuit 1. When the reproduced PW does not coincide with the input PW, reproducing is not performed, thereby keeping the secrecy in the case of reproducing.
