I believe there's a misunderstanding or a typo in the search query "jvs flying erase hea vcrs". It's not a standard phrase or recognizable technical term. To help me understand what you're looking for, could you please clarify? Are you referring to:
- Specific brands or models of VCRs? Perhaps "JVS" and "HEA" are parts of model numbers or brand names? Providing more information about the VCRs would be helpful.
- A particular function or feature? "Flying erase" sounds like a technical term related to the recording or erasing process. Are you interested in how VCRs erase tapes, or are you looking for information about a specific type of erasure method?
- Troubleshooting a problem? Are you experiencing issues with your VCR, such as inability to erase tapes properly? If so, please describe the issue in more detail.
Once I have a clearer understanding of your query, I can provide more relevant and helpful information.
