NT cassette compared to various memory cards. The design was a rotating head based system which stored memos using helical scan on special microcassettes, which were 30 mm × 21.5 mm × 5 mm with a tape width of 2.5 mm, with a recording capacity of up to 120 minutes similar to Digital Audio Tape.
Battery life is shortened due to the fixed (CAV) read speed of the disc and power required by the memory. Older players (1992–1997) had at most half the battery life when the skip protection system was in use. Players from 1997 onward have more power-efficient skip protection.
On Sony's machines, this automatically selects 70 μs equalisation. The service manual for the Sony TC-135SD, which was one of the few cassette decks offering a 'Fe-Cr' position, shows the tape type selector switch paralleling the ferrichrome equalisation selection with that of chrome dioxide (70 μs).

The first consumer tape recorder to employ a tape reel permanently housed in a small removable cartridge was the RCA tape cartridge, which appeared in 1958 as a predecessor to the cassette format. At that time, reel-to-reel recorders and players were commonly used by enthusiasts but required large individual reels and tapes which had to be ...
D-1 or 4:2:2 D-1 (1986) was a major feat in real time, broadcast quality digital video recording. It stores uncompressed digitized component video, encoded at Y'CbCr 4:2:2 using the CCIR 601 raster format with 8 bits, [1] [2] along with PCM audio tracks as well as timecode on a 3/4 inch (19 mm) videocassette tape (though not to be confused with the ubiquitous 3/4-inch U-Matic/U-Matic SP cassette).
Tape transport with dual pinch rollers - Technics RS-1520. A tape transport is the collection of parts of a magnetic tape player or recorder that move the tape and play or record it. Transport parts include the head, capstan, pinch roller, tape pins, and tape guide. The tape transport as a whole is called the transport mechanism.
[2] [3] Through the 1980s and 1990s, Sony created many versions and variations in the cassette tape Walkman line [4] such as the DD series and WM series. Below is an incomplete list of cassette tape based Walkman models. Sony Walkman TPS-L2, from 1979. Sony Walkman WM-F15, released 1984. Sony Walkman WM-28, early 1980s Sony Walkman WM-F77 ...
Compared to Quad, Type C had a smaller size, comparative ease of operation, and slightly higher video quality. 1-inch Type C is capable of "trick-play" functions such as still, shuttle, and variable-speed playback, including slow motion. 2-inch quadruplex videotape machines lacked these capabilities, due to the segmented manner in which it recorded video tracks onto the magnetic tape. 1-inch ...
