Re: QL replica

That's one large print bed you have to get the full-size QL printed.

Re: Solid State Microdrive Cartridge?

I have a Panasonic micro-cassette recorder https://www.amazon.com/Panasonic-Microc ... 00855ZODA/:

Measured its head an it is only about 5 millimeters, so they do make them smaller. Where to source them though, I don't know.

Re: Solid State Microdrive Cartridge?

That was also my understanding - that if the QL was writing data - it would be present on the head, and would not be there if we were reading - it would expect the tape to be providing it. I would think for reading vs writing, there would be a voltage passing through the magnetic coil in either ins...

Re: Solid State Microdrive Cartridge?

Not quite. Checking the erase coil would not be done for erasing anything, but to actually detect when to write. In this setup, it's the only way how we can discriminate between reading and writing, since we don't have access to the R/W line of the Microdrive bus. Oh interesting. I guess I was unde...

Re: Solid State Microdrive Cartridge?

So I looked this up online and found pictures of a normal cassette player ( https://www.tapehead.org/en/reparatie/draagbare-toestellen/sony-tcs-370-r/ ) and a micro cassette player ( https://www.tapehead.org/en/microcassette-info/ ) that used the same head. Here I've cut/pasted the closeup of each t...

That's great and should solve techy's problem. I highly recommend vDrive. It's one of my favorite extensions to the QL!

Re: Solid State Microdrive Cartridge?

Hi, I might be wrong but the tape in an ordinary audio cassette is 3.8mm and just 1.9 mm or maybe 2mm for a QL same as smaller cassettes used for dictaphones I have a micro cassette recorder and I'll have to look at its head. The tape size for the QL isn't that much smaller than a normal cassette s...

Re: Solid State Microdrive Cartridge?

...you would also need to detect when to read and write. For this you have to check whether the erase coil is emitting a field, and as soon as it does, start reading what the tape head is emitting. Once the erase field is gone, you then switch back to replaying the data into the tape head. Seems al...
