Maxell LN 25 - 120 Sound Recording Tape (Low Noise) / Extended Range SET OF 2 (TWO) - For Professional Use, probably recorded

The Maxell LN 25-120 

is a vintage 1/4-inch reel-to-reel open-reel magnetic audio tape manufactured by Maxell. 

Technical Specifications

The code sequence used in the model name directly breaks down the tape's physical dimensions and layout:

• LN: Stands for Low Noise, which was Maxell's ferric-oxide.
• 25: Refers to the total thickness of the tape base, which is 25 microns (0.75 mil). This classification makes it a Double Play (DP) thin-profile tape. 
• 120: Indicates the recording run-time of 120 minutes when recording both directions combined at standard speeds.
• Physical Length: The reel holds 2,400 feet (approximately 740 meters) of tape spun onto a standard 7-inch (18 cm) spool hub.

Performance Characteristics

• Excellent Longevity: Unlike many vintage tape brands from the 1970s and 1980s (such as Ampex), Maxell formulas use a robust binder. They are celebrated by collectors because they do not suffer from Sticky-Shed Syndrome (SSS) and will not turn gummy or squeal during playback.
• Handling Caution: Because it is a thinner 25-micron "Double Play" tape, it offers more recording time per reel but is more prone to stretching, wrinkling, or print-through (ghost echoes) if played on heavy-duty or aggressive vintage tape decks.
• Sound Quality: It provides decent, stable fidelity for general consumer home recording.
