Title: Slip check system in magnetic tape device
Inventor: WADA TADAHIRO
IPC: G11B15/28
Filed: 1979-03-30
Abstract: PURPOSE: To check slip more exactly by starting write modulation when the speed does not reach a fixed value and by comparing tachometer pulses at this time with data pulses.  
     CONSTITUTION: The output of tachometer 5 is counted as pulse intervals by tachometer pulse sensor 6 and the second counter 7, and the first and the second speeds are detected by speed detection means 9. Now, when the first speed Va is detected, modulating circuit 11 is started to start write. When written data reaches read head 4, the output counts data pulse intervals through the first counter 14 and is applied to synchronizing detector 16. Meanwhile, the third counter 10 starts counting by the output dependent upon the second speed Vb and stops counting when synchronizing detector 16 detects a prescribed period. Then, the output of the third counter 10 is compared with the reference value for no slip by comparator 20 to detect whether slip exists or not. Thus, slip can be checked more exactly.
