Compatibility of VCR tape speeds
I want to tape some cable programs for a friend who does not have HBO
& mail them the cassettes. My VCR supports SP, LP & SLP. Their VCR supports SP & EP. I see on the tape box (T-160) that both EP & SLP provide 8 hours of recording. This is the speed I generally use and prefer due to the recording length, but the last time I prepared a tape for the VCR in question, the audio was very muffled. I tried the tape on another VCR in the area, it too was muffled. I'm not sure what the available speeds were on this 2nd VCR, but it was pretty old. I had attributed this sound degradation to the fact that I had taken the tapes to my friend on an airplane, & it occurred to me the tape may have been effected by the x ray security scan (I realize x rays by themselves would probably not have this effect, but it seems possible a magnetic field in the x ray machine, perhaps from the large high voltage transformer x ray units generally contain, might have harmed the tape). So my question (FINALLY! ;-) is will a tape recorded on my machine in SLP play on a machine with the speeds SP & EP? TIA David |

Compatibility of VCR tape speeds
Dan:
The slower speeds like LP (4hrs) and SLP/EP (6hrs) are always a compromise of picture and sound quality.... and if VCR interchange is less than perfect you may end up with tracking problems and sound problems..... you would be best advised to stay with the Standard Play (SP) speed if at all possible for best results. Most VCRs manufactured in the last 5 years do not record in the LP (4 hr)speed. Even if the playback VCR does not "support" (or record) in all three speeds, i.e. SP, LP, SLP/EP it will still playback in all three of those speeds. SLP and EP speeds are the same thing, just that different manufacturers called them different names..... Super Long Play and Extended Play ...... Most tech types will keep all of this crystal clear by identifying the speed in hours on a T120 tape: SP 2 hr speed LP 4 hr speed SLP/EP 6 hr speed -- Best Regards, Daniel Sofie Electronics Supply & Repair - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Dan" wrote in message om...

I tried the tape on another VCR in the area, it too was muffled. SLP = EP = 6 hour. Same speed just different terminology. More likely you have a stero vs. mono compatibility problem. Two skinny heads playing one wide track = no problem. Wide head playing two competing skinny tracks plus dead band between = not so good. Other possibilities: weak or incorrect recording bias, head/ tape path alignment problem. |

Compatibility of VCR tape speeds
With home type VCR's I found that the speed is not the problem. It is
usually the tracking accuracy from one machine to the other. In the SP mode there should not be any difficulty. In the LP, and SLP modes, there may be a tracking problem between the machines. -- Jerry G. ===== "Dan" wrote in message om...
