The speed of a tape recorder varies depending on the type of tape and its intended use, but common speeds include 1+7⁄8 in/s, 3+3⁄4 in/s, and 7+1⁄2 in/s.
Tape recorder speed refers to how quickly the magnetic tape moves past the read/write head. Different speeds offer varying levels of audio quality and recording time. Higher speeds generally provide better fidelity but consume more tape.
Here's a breakdown of common tape speeds:
-
1+7⁄8 inches per second (ips): This speed was primarily used in compact cassettes. It offers a longer recording time but at a lower audio quality compared to faster speeds.
-
3+3⁄4 inches per second (ips): This speed was frequently used for commercial reel-to-reel releases and 8-track cartridges. It provides a balance between recording time and audio quality.
-
7+1⁄2 inches per second (ips): This speed was also common for commercial reel-to-reel tapes, offering higher audio quality than 3+3⁄4 ips.
Summary Table:
| Tape Type | Speed (ips) | Characteristics |
|---|---|---|
| Compact Cassette | 1+7⁄8 | Longer recording time, lower audio quality |
| Reel-to-Reel, 8-Track | 3+3⁄4 | Balanced recording time and audio quality |
| Reel-to-Reel | 7+1⁄2 | Higher audio quality, shorter recording time |
Therefore, there isn't a single answer to the question of "what speed is a tape recorder." The speed depends on the specific application and the format of the tape.
