Title: Magnetic recording and reproducing device
Inventor: YAMAMOTO MASAKAZU
IPC: G11B15/46
Filed: 1989-04-28
Abstract: PURPOSE:To prevent a tape end from being damaged and simultaneously to make a time required for rewinding short by detecting the rotating cycle and the rotational frequency of a take-up reel and a supply reel and controlling them to the neighborhood of the tape end at a high speed. CONSTITUTION:In the case that the rotating cycle of the reel on the taking-up side is set (lambdat), the rotating cycle of the reel on the supplying side is set (lambdas) and it is (lambdas) > (lambdat) when reproduction (or recording) is started from the starting end of a tape, r = lambdas/lambdat is calculated. Next, when a rewinding mode is selected, low speed rotation is executed, first and the rotational frequency of the take-up reel (ft) and the rotational frequency of the supply reel (fs) at that time are detected. When, it is (ft) > (fs) and (lambdas)/(lambdat) > (ft)/(fs) or it is (ft) > (Fs) and (lambdas)/(lambdat) > (fs)/(ft), the rotational frequency of the reel is set at a high speed. Next, the rotational frequency Ft of the take-up reel and the rotational frequency Fs of the supply reel at the time of high speed rotation are detected. Then, R = Fs/Ft is calculated and compared with (r) which is calculated before. The low speed rotation is executed again from the position where conditions that (r) <= R, that means, (lambdas)/(lambdat) <= Fs/Ft is obtained is satisfied.
