Title: Magnetic recording and reproducing device
Inventor: YANAGAWA HIROSHI
IPC: G11B5/55
Filed: 1988-11-30
Abstract: PURPOSE:To shorten time required for the operation of detecting a tape end and to reduce stress put on a tape by giving a function which records a signal to an erasing head. CONSTITUTION:The signal is recorded on an area 6 by the erasing head 5. At this time, since a reproducing head 3 is positioned on a recording area, a reproducing signal is obtained when the tape is made to travel. Next, since the reproducing signal disappears when the reproducing head 3 arrives at a position C after it is gradually moved toward the tape end while making the tape travel and moved as much as a distance (d2), the reproducing head 3 is moved toward the tape end while making the tape travel in the same way after the signal is recorded again on the tape by using the erasing head 5. In the case that a recording end is detected when the moving distance of the reproducing head 3 is under (d2), the detected position is regarded as the tape end. Then, since the recording area by the erasing head 5 is wider than that by the reproducing head 3, the distance (d2) by which the head can be moved at a time can be made long. Thus, the time required for detecting the tape end and the stress put on the tape are reduced.
