The tapes are containing music from 80`s. They are 2 track recordings at 38 cm/s. Type of Tape: LP stands for "Long Play". This designation means the tape is thinner than standard-play (SP) tapes, offering double the recording time compared to an equivalent standard tape on the same size reel. Length: A typical 10.5-inch LP 26 tape provides approximately 1,080 meters (around 3,600 feet) of recording material. Recording Time: This length allows for significant recording time, such as roughly 90 minutes of stereo recording at 7 ½ inches per second (ips), or 3 hours at 3 ¾ ips.
