What size tapes does this recorder take? - Philips Desktop 710-T Desktop Cassette Transcriber / Recorder

I assume you have reel to reel 1/2 inch audio tape.
You will have to find a tape machine that uses the same size, format and speed as the 1/2 inch tape was recorded at in order to play it back (Presumably, you will record it into a DAW or computer digital audio format for future use?).
This tape could be a multi-track in a format specific to the original machine it was recorded on, it could be digital audio on reel to reel tape, it could be many different formats.
What do you know about the tape, how, when, and on what equipment it was recorded?

You can try this site that I am listing but if it is not in stock, then you can use the dimensions listed to see if you can find one. SMC ELECTRONICS

Hello may be you try to say what type of tapes used your unit, if yes it is a micro cassette size see link for some available for your unit. http://www.tvps.com/Departments/Dictation-Accessories/Cassette-Tapes/Micro.aspx

I believe that was vhs-c format.
Your best bet would be ebay.
Try searching for vhs-c adapter.
I found a few in the $10-20 range.

Have you tried cleaning the recording heads? Use a dry type cassette cleaner only. It's just like a vcr head cleaner tape, only in the small mini-dv tape size.

You need to use longer tapes. The DER-11 is a DVCAM deck which when recording, uses a faster tape speed then mini DV. Think of your older VCR's. They had SP, two hours, and EP or SLP, which would be six hours. The SP speed would give a better picture. DVCAM is more like an SP recording except digital and a lot better. More information is laid down on the tape.

You'll have to jump up to the full size DVCAM tapes in order to record the full hour.

THERE IS A TAB ON THE VCR TAPES IT CAN BE BROKEN OUT TO KEEP PEOPLE FROM TAPING OVER YOUR PERSONAL TAPES.LOOK AND SEE IF THIS IS NOT BROKEN OUT. IF IT IS PUT SOME TAPE OVER IT AND IT WILL RECORD ON THAT TAPE AGAIN.

I assume you want to record from a tape recorder/player. If not, leave a message, but it will be a similar cable and connection.

If your tape recorder has a headphone jack, you can connect it to your sound card with a special cable. The headphone connectors are sometimes different sizes. It could be either a 1/8 inch, 2.5 mm or 3.5 mm plug. Your local electronics supply store (Radio Shack?) should have the cable you need. (I'd take your tape recorder with you, if possible.)

The physical tapes are the same size, but the encoding on the tapes are different. Unless the panasonic recorder can play DVcam, you're out of luck.
