There is provided a substrate processing system comprising: a plurality of transfer modules having transfer mechanisms configured to transfer substrates; and a plurality of process modules connected to the plurality of transfer modules. The transfer mechanisms of the plurality of transfer modules transfer a plurality of substrates sequentially and serially to the plurality of process modules, and each of the plurality of transfer modules has an aligner configured to align a substrate when transferring the substrate to the process module connected to a relevant transfer module.

The present disclosure generally relates to a tape head and a tape drive including a tape head. The tape head comprises servo heads configured to read servo data from a tape, a plurality of write heads configured to: write user data to a plurality of data tracks of the tape and write embedded servo data into one or more data fields of the tape, the embedded servo data comprising servo positioning information, and a plurality of read heads configured to read the user data and the embedded servo data from the tape. The embedded servo data may be embedded servo fields or embedded servo tracks. The embedded servo data allows the tape head to be accurately controlled and positioned above the tape, and for new data to be accurately appended to the tape.

Devices, systems, and methods for detecting user devices to determine a state of a watched show are provided. A digital video recorder (DVR) is configured to store a media file associated with a media program. The DVR detects one or more user devices within a predetermined vicinity while the media program is being played. The DVR identifies users who are interested in the media program. The DVR tracks a watch status associated with the media program indicating which users have watched or are watching the media program based on the detected user devices. For stored media files, the DVR determines whether to delete the media file based on whether all users who are interested in the media program have completed watching the media program. The DVR may track user activity and/or vital signs based on sensor data from wearable devices, for example, to determine user reaction and/or user interests.

A data storage device configured to access a magnetic tape is disclosed, wherein the data storage device comprises at least one head configured to access the magnetic tape, wherein the head comprises a write element, a first read element substantially aligned with the write element, and a second read element laterally offset from the first read element. Data is written to a data track and read-after-write verify is performed using the write element and the first read element. In response to a read command received from a host, the data track is read using the second read element to compensate for a stretching of the magnetic tape.

A data storage system includes a data storage foil mounted within the data storage system, the data storage foil has at least one data storage surface. The data storage system also includes a head configured to interact with the at least one data storage surface to carry out at least one of data read or data write operations.

A data storage device can have one or more timestamps to indicate chronological information associated with data stored in the data storage device. A controller may be connected to a timestamp module and a transducing head to allow a timestamp to be written to a magnetic data storage medium as directed by the timestamp module. The timestamp can consist of chronological information relating to user-generated data stored on the data storage medium.
